Silicone sex toys have come a long way, baby. I often am asked to give someone my opinion on whether or not a sex toy is actually the silicone it claims to be. When the material is opaque it’s hard to tell visually but the proliferation of clear jelly/TPR material in sex toys gives me a leg up in making a call. I’ve frequently warned on my blog that “clear silicone sex toys won’t be crystal-clear, they’ll be cloudy-clear”. Yet earlier this year I was reassuring multiple people that a new guy on the block, Funkit, was definitely creating clear silicone sex toys. Why the panic? Probably because my differentiation between “crystal clear” and “cloudy clear” is skimmed over and the focus is on “clear”. Today I’m hopefully going to give you better tools, and a better understanding, of the differences between clear silicone sex toys and clear TPR sex toys if you don’t want to, or can’t, do a flame test.  And while Funkit isn’t the only brand to use clear silicone it is the brand people have asked me about the most lately. Other brands that have used a clear silicone include Vixen and Vamp; you’ll notice Vixen using it in their Hitachi Wand caps. Vamp uses a clear silicone but heavily infuses it with glitter. A brand that has been around awhile, quit, moved to Etsy, quit again was Jollie/Chavez Dezignz – they made the polka-dot dildo many of you would remember.

Clear As….Water?

In many past posts I’d used the terms “crystal clear” to describe what PVC/TPR/Jelly toys look like and “Cloudy Clear” to describe what clear silicone toys look like. Kenton, the ingenious person behind Funkit, graciously allowed me to pick his brain to help better explain things to y’all. According to Kenton the term “water-clear” is a better descriptor to use, and he’s right (unless your water isn’t clear…). While both materials are certainly translucent (and thin samples of clear TPR might even be considered transparent), the silicone we would want our sex toys to be made of can never be water-clear. There is water-clear silicone, something Kenton reminded me of that Metis told me a long time ago; but it isn’t a sex toy material, because it gets brittle and doesn’t hold up well, plus is very hard.

Cloudy-Clear vs Water-Clear

When it comes to a relatively thick chunk of translucent silicone, like the head of the Funkit dildo shown below, you can see that it wouldn’t be called water-clear. This is the perfect example of “cloudy clear”. Even with the Funkit silicone paddles, as thin as they are, you can still tell that it’s kinda cloudy. But as you can see below the head of the TPR vibrator is as thick as the head of the Funkit dildo – And as thick as it is, it’s still a lot more translucent than the clear silicone.

Most clear silicone sex toys will never be any less cloudy than this, which is considerably less water-clear than translucent TPR

If you’re still unsure, and you can see it in person Kenton told me about the light trick, which is pretty neat:

Visually, cloudy clear, but highly transparent silicones often lend an amber hue to light that passes through them, especially thick parts. This is true of my toys, at least, and all the silicones I’ve worked with, including many Wacker samples and Reynolds Advanced Materials. That’s a pretty good test, but flame testing is still important.

When I just held my LED light up to it I didn’t really notice what he was talking about but the moment I shone the light through the material onto a white surface, the answer was clear. Below this paragraph in the photo on the left I’m shining my light through a Funkit Swing dildo; you can see the light that passes through is very amber-yellow. The photo on the right shows the same light shining through the head of the Tracy’s Dog not-silicone rabbit vibrator. There’s no color distortion to the light as it passes through.  I don’t know how this test would fare if the clear silicone were tinted, like many water-clear TPR toys, such as this. Kenton has said that it is possible to all-over tint the clear silicone like that, he just doesn’t do it.

Shining a bright light through clear silicone sex toys distorts the white light to a warm amber Shining a light through a clear TPR sex toy won't distory the light color

Price, Brand, Feel

Price, and brand reputability, will give you many clues. The brands you will see claiming their water-clear material is silicone are nearly never being sold through reputable retailers and are almost always under-$40. One brand that I’ve only seen on Amazon, the terribly-named Tracy’s Dog, is one example. While the company does produce silicone items that are indeed silicone, they also sell items like the rabbit vibrator in my pictures – priced at $13.98, you won’t find clear silicone sex toys for that price. But what if it’s a frosty translucent material, from an Amazon brand, and cheap? Is it silicone? I think I’ll have to purchase it and do a flame test. I do know from my trials with items listed on Amazon as “silica gel” that you can have a soft, nice-feeling frosty translucent item that is NOT silicone. The “guess by looking” isn’t fool proof, obviously, but we have to start somewhere. However, the more clear the silicone is, the better the quality of the silicone, the higher the price.

Another clue is confusing listings with poorly-translated ad copy. As you’ll see from these Amazon listings the material can be described as silicone, TPR, and medical silica gel all in the same listing. “Medical silica gel” is not a sex toy material so when in doubt always assume the lesser material if you can’t tell just by the level of transparency.

I mentioned price up there when I talked about the cheap items you might find on Groupon, Amazon, AliExpress or Ebay. But not all PVC/TPR rabbit vibrators are cheap. For reasons I’ll never understand companies like Doc Johnson and CalExotics, or Evolved Novelties sometimes charge a pretty penny for TPR rabbit vibes – but at least they’re honest now in the materials description, and call it TPR – so long as you’re shopping with a reputable retailer.

Often when you see bigger brand clear silicone sex toys, like this silicone rabbit vibe, the silicone is more cloudy (frosted?) than the stuff used by Funkit, Vixen, Vamp, etc. It could be down to a difference in shore, silicone type & quality (medical, food grade1, etc) or silicone price (the more clear, the more expensive). It could also be a difference between RTV silicone that is hand-poured and LIM or liquid injection molding.

Feel – this one is harder to put into words, for me. Often a TPR or PVC clear material can feel a bit oily, but not always. When I was trying to find a word to describe what I was feeling, what came to mind was “squeaky” but that’s a sound, not a word. I can rub my thumb over these materials and I actually kinda can hear a sound. When I’m done rubbing my hands over these materials, if they don’t feel obviously oily, my the skin on hands still is left feeling strange – like there’s a chemical residue. I don’t experience any of this with silicone. The only residue that’s been left on my hands after fondling some silicone is a silky feeling. I think that once you can feel both materials side by side, you’ll always know how to tell in the future.

Thanks Kenton!!

Kenton Johnston is the man behind Funkit, and he’s creating some pretty amazing stuff. Yes, the vivid swirls of pigment suspended in translucent silicone is different and gorgeous but he also is thinking way outside the box – from his unique suction-cup-and-butt-friendly base design to these really cool hand sex silicone texture rings he’s trying to get funded on Indiegogo – I’ve seen them in person and I definitely think they’ll work as advertised. He’s a big sex geek, like us, and fortunately was happy to let him pester him with all sorts of questions to help me easily show you how to tell if these clear silicone sex toys are really true to their advertising. For now you can buy Funkit products direct, but I hope that soon he’ll get his stuff into the hands of progressive retailers like Early to Bed, Smitten Kitten, and Shevibe.


Clear silicone sex toys, even when the material is thin like the base of this Funkit dildo, are still more cloudy than transparent TPR

Find Funkit on Facebook, Twitter and Instagram.

  1. Medical grade isn’t everything, and I feel confident now recommending other grades especially when it’s listed as food grade. Kenton told me that “Food grade silicone is tested to FDA standards for food safety, which involves submerging a sample on ethyl alcohol, water, oil, and acetone and seeing if anything leaches out in any of these. If harmful substances come out of the material, it is bad, and should feel bad. Medical grade silicone has to be able to be implanted for a certain amount of time, and is tested differently for different duration. There’s also medical silicone for prosthetics, and this has its own tests as well. Medical grade silicone is also made in cleanroom settings. The thing is, a sex toy is something that is most likely going to come in contact with mucous membranes. It is not going to be implanted into your body. Anything that is safe for food necessarily has to be safe for mucous membranes like your mouth and anus, so food grade is a perfect fit for sex toys. While medical grade sounds better, it’s really overkill for the cost it adds, considering the extra effort in testing doesn’t add anything for a simply sexual  purpose.”

So I get a fair amount of people coming to me in fear, in panic and mostly in pain because they used a lower-quality sex toy made from a dubious material or a material that contains a supposedly “helpful” additive (hey, lookin at you Sil-a-gel) and they want to have their fears alleviated but also, you know, not be in pain. I’ve read the fear in emails from people terrified they have caused themselves some sort of permanent damage; or they went to their doctor who probably frowned and loosely diagnosed them (if they have a vagina) with BV or maybe a yeast infection. Maybe these people told their doctor about their sex toy. Maybe they themselves didn’t know that the sex toy could be the cause of their vaginal burning until they read my old post about jelly dildos or my newer post about Sil-a-gel. Regardless, they’re in pain and scared and want to be neither. Or, maybe, they used a lube with a nasty chemical in it that they have now reacted horribly to. I’ve read about mild chemical burns from shitty lubes, too.

I’m not a doctor. I’m not a medical professional of any kind. I did vet these solutions with a midwife, but you may want to check with your own doctor first. When you speak to your doctor, be honest about what is causing the problem, be it sex toy or lube. At the very least you’ll be educating your doctor because many of them don’t know that this is happening. Ask them for treatment advise for a chemical irritation/burn.

If You’re Pretty Sure The Burning Pain is From Your Sex Toy

And you are certain it is not made from silicone (and I mean CERTAIN), glass, or hard plastic – we then must assume there is some chemical in the softened plastic/vinyl (PVC is the usual culprit, possibly rubber, maybe some mystery material) that is causing this and that said material has probably begun to leach oils and break down. You may experience lingering pain and burning because the bad chemical is attached to an oil and you’re not getting the oil off your genitals. So first, let’s get those oils away from your sensitive mucous membranes.

Plain water douche OR milk douche (not skim milk) – The plain water may help, but the proteins and fats in the milk may be better. You know how when you eat something WAY too spicy from peppers and cold milk eases your pain? Same concept. This should be avoided if you’re allergic to cow’s milk. I do not know if non-dairy milks will help here – as Lorax explained their reasoning to this suggestion it was based on the proteins and fats in the milk.  You can expect to need to do this a few times over the first few days. You can also just buy a quart of organic cream and add it to water and do a sitz bath. Try both tepid water and cool water for this, see which gives you more relief. If your water is treated or hard water you may want to consider using filtered water or distilled water for this. You can get a sitz bath for your toilet at any pharmacy, they look like this.

While you (probably) don’t have a yeast infection, you might consider a vinegar douche as described here. It may help get rid of the oils, and it will also kinda reset your pH which will be helpful if part or all of the problem is that you used a lube with a pH much lower than your own.

Yogurt Everywhere – but first, the warning: You must use plain, unsweetened, unflavored organic yogurt. Anything else is bad. It would be best if it has live, active cultures. If you think that most of the burning is external then just generously frost your vulva with cold yogurt and lay there in awkward positions in the bathroom while it works some magic. If you think that some of the burning is also interior then get a plastic tampon applicator (unscented, please), toss the tampon, and fill up the applicator with yogurt. You could also use a needle-less syringe or a very clean turkey baster.

A note: While I most often hear about burning vaginas and vulvas, this could happen to the rectum/anus as well I believe. I don’t see why these things wouldn’t work for the butt – just get an enema kit from your pharmacy.

These methods will soothe & cool the inflamed tissue and remove the oils. Now what? Your flesh is still sore and inflamed so you need to keep babying it.

Methods to Soothe Inflamed Genitals

In between rinsing and sitz-ing to make sure you removed the chemical that is burning your vagina or vulva, you need to calm down the inflammation and help yourself heal. Since vaginal burning isn’t limited to sex toys, if you have vaginal burning and it’s not a sex toy or infection, look at your lube. If the pain lasts only while you’re using the lube and for a little while after, it could either be a pH imbalance or a bad ingredient. Read about that here, and get yourself some pH strips to test you AND the lube. Most likely if you’re reacting badly to a crappy lube, there’s no oil involved – unless it’s one of those warming/cooling lubes, then YMMV. If the following methods don’t give you relief, go up and try the yogurt or milk tricks.

Get an old fashioned menstrual pad (not the dry-top-layer kind, the cheap kind) or even just some clean fabric / fabric pads. Soak it in chamomile tea and then refrigerate the whole thing a bit. You want it cold. Let the chamomile tea + the chill of it all calm down the inflammation. Repeat as necessary.

For external use only, a midwife also suggested hydro-cortisone cream if things are really bad.

If you have access to it, a CBD or THC infused coconut oil salve will really help speed up healing. If you’re in Canada look for Cannalife products, especially the salve.

Ice – but please use a barrier like a thin washcloth so that you don’t burn your skin from the ice. I bet anything your local grocery store (where you’re already headed for yogurt, chamomile and pads or tampons) has an ice cube tray like this in their drinks aisle. The long, round slender shape can lay nicely between your labia. It can slip into a condom1 (giving you a little protection from the cold and tied off so that you don’t soak the bed) and then be inserted vaginally (hey, smear it with yogurt for a double-attack – yogurt as lube and soother). Smitten Kitten sells a thing meant just for the genitals but you probably don’t want to wait on the shipping.

You’re probably a bit drier than normal right now so consider moisturizing with organic, unrefined coconut oil (unless you’re allergic). Other natural oils can help, too, like grapeseed. It seems that most people that will react badly to oils around their vulva react to refined oils (like Vaseline). Keep in mind that oils destroy latex and polyisoprene, so if you insist on having sex, use polyurethane condoms.

Wear loose, soft underthings and avoid sex and masturbation until you’re fully healed.

Please let us know in the comments if anything else has worked for you!

This post is brought to you by a blogger roundtable on-the-fly had in the Tantus Blogger Lounge at Woodhull’s Sexual Freedom Summit 2016 (where SheVibe was my sponsor). Many suggestions from the incredibly smart Lorax of Sex, with ideas also from Taylor and Caitlin. I thank you smart folks, and my readers will thank you. As we all tossed around ideas I started frantically entering them into a notes-taking-app on my phone; my phone which kept auto-correcting “douche” to “douchecanoe” and I had to just let that go, knowing I would understand the notes no less in a week or two.

Today we're talking about Doc Johnson sil-a-gel sex toys, and why they're causing chemical burns on genitalsOn the days that I wonder if I’m still relevant, if I’ve done enough of worth1 to make this blog helpful, I have to remember situations like this email. My heart absolutely sunk as I read it. I was grateful that I wrote about Doc Johnson sil-a-gel additive and all of its problems so that this reader could get the truth on what could be happening to her, but I am so angry that this is happening. WHY IS THIS HAPPENING, DOC JOHNSON??? Why do you insist on trying to polish the turd that is heavily-softened PVC by boasting about some mysterious “anti-bacterial” chemical that you add to your porous materials? A chemical that is clearly NOT rainbows and puppies judging by the number of people who have told me that their Doc Johnson sil-a-gel containing sex toy caused rashes, redness, small blisters and extreme pain.

Because I am not a doctor, and some parts of this email concern me even more, I’m sharing this with you, dear readers, to see if anybody can chime in. I’m also sharing this story because I want to know how many complaints like this will it take for Doc Johnson to ditch the sil-a-gel?

Although I have been very sexually active from a very young age I have always had an aversion to sex toys and never tried them. An accidental pregnancy put my libido into extreme overdrive while at the same time isolating me from my husband due to stress and tension, so I emotionally braced myself and decided to join ranks with all of the other women I know by masturbating with a Doc Johnson double ended dildo I received at my roller derby team’s white elephant christmas party. 

I have been suffering from repeat bouts of what I first thought was a yeast infection or BV, because of extreme itching and burning on my inner labia, but I haven’t had any discharge or foul odors. It literally feels like a chemical burn and often causes my clitoris to swell and the skin to peel. 

My list of drug allergies is like a mile long, including benzocaine, lidocaine, and micronazole and I get contact dermatitis from most soaps and anything that contains fragrances so I have always been very careful about what I put on my skin. My midwife suggested that it must be an allergic reaction to my husband’s body soap, the pH of his semen, or just my sensitivity to the pH and hormonal changes caused by my pregnancy. The only thing that seems to “calm” it is an ice pack followed by a thick layer of vaseline. 

As weeks went by, I realized my husband was intentionally avoiding sex with me and I suspected he might be having an affair, so then I worried that all of it could be an STD. I accused/confronted him but all my tests came back normal and he explained that he too had experienced a rash on his penis after having sex with me and didn’t want to get it again. We tried condoms (non latex) but it happened again AND I have also been suffering from an irritable uterus which means I get pre-labor contractions that force me to lie down and relax, so he pretty much decided we should just abstain from intercourse while I’m pregnant.

So out of sexual frustration I began using that dildo even more regularly, but really I am tired of it and it doesn’t provide the intimacy that I am craving. Desperate to figure out how to end this vaginal irritation, it dawned on me that the combination of petroleum and the rubber dildo might be a problem since I know you aren’t supposed to use vaseline as a lube with condoms so I began researching it and stumbled across your piece about Doc Johnson Sil-a-Gel.

So now I feel like “Eureka!” that’s got to be the root of my problems, but what are the full consequences? Obviously I am ditching that dildo and being such an awful first experience I doubt I will ever try a different sex toy, but how long will it take for me to heal?  And more importantly are there any documents or studies concerning phthalate toxicity during pregnancy??? I know this is a super long email and that you are not a doctor, but I am pretty freaked out and would appreciate any guidance, information, or direction you can give me.

So let’s delve into a few things first. Dear reader, please don’t let Doc Johnson sil-a-gel ruin you for sex toys. There are thousands of true, body-safe sex toys out there that won’t cause reaction – silicone, aluminum, stainless steel, glass, wood, and hard plastic to start with. Because I can’t recommend a dildo without knowing much more information, I’m reserving that for future conversations with the reader. Secondly, I’m not a fan of Vaseline in the vagina or on the vulva, so let me suggest some organic, non-refined coconut oil to help protect and moisturize the irritated skin without affecting your pH – only if you know you aren’t allergic to that. A small percentage of people are.

For those willing to make educated guesses and suggestions here, I do want to note I’ve already discussed lube with the reader, and know that it isn’t the cause of her problems.

As I researched the Doc Johnson “Ask The Doc” archives for some more info on their sil-a-gel products, I briefly pondered submitting my question about why people are experiencing chemical burns from using a Doc Johnson sil-a-gel containing sex toy. But then I came across so many flippant AND WRONG answers from whomever is in charge of this page that I am just absolutely stunned. Completely gobsmacked. I can only assume that Doc Johnson is never going to admit that there’s a chance that something about sil-a-gel is caustic and stop using it in their sex toys. They repeatedly advise their customers that it’s safe to use oil/oil-based lubes on their PVC dildos. Um, no, no it’s not. How about we look at this jar, which began with one large chunk of PVC as part of the dry mix and quickly degraded from the oils put out by other sex toys in the jar? Then they tell their customers that it’s safe to put their dildos in the dishwasher. Subjected to heat. A: this won’t do any goddamn good for getting it “clean”, because it’s porous and 2: ARE YOU FREAKING KIDDING ME? I don’t believe for a minute that softened PVC will withstand the heat of a dishwasher.

Customer asks: Can I use silicone lube with silagel? Doc Rep answers: "Yo...So Sil-a-gel is an antibacterial compound that we add to our "Made in America" products. It is not a coating or a separate material. It is added into our material in the raw mixing phase so that the antibacterial agents are actually engrained into the product and will not wash away with use. Although you should always wash your products with mild soap and water, Sil-a-Gel is our way of going the extra mile to make sure that your products are as safe and clean as they can be"

Customer asks: Does platinum silicone have platinum in it and is it 100% silicone". Doc Rep answers: "Just silicone....the Platinum is like... when you get a Platinum credit card it's not platinum. At least mine isn't"

*facepalm* Yes, actually, there are trace amounts of platinum left behind and they can be detected in lab tests. It’s called platinum silicone because platinum, the mineral, is used as a curing agent. Not because it’s like a “platinum credit card”. For fucks sake, really?

Customer asks: What grade is your platinum silicone toys (ex: food or medical grade)? Doc Rep says: "that would be health grade"

Um….can you show me what “health grade” is, by definition? Can you tell me it’s even a thing? Because I can’t find that.

Customer asks if coconut oil is safe on PVC, Doc Rep says "we don't test coconut oil on our items. But as far as I know PVC is a very hardy material and if you wash right after use it should be fine"

So here we have one of many answers that the person/people behind this section of the website should really just answer with a ¯\_(ツ)_/¯ BUT WAIT, THERE’S MORE:

Customer notices that they see answers here saying that PVC can be used with "any lube we like" which they assume to also include oil-based lubes, but every other website says that PVC degrades from oil (which, it does). They ask what lube they SHOULD use. Doc rep says "R5 (PVC) can be used with water based, silicone, or hybrid lubes".

Here they kinda get vague, by not really answering the question directly. And yes, every other website DOES say PVC degrades from oil, because it’s true. So while they won’t outright admit they’re giving wrong info, they vaguely say that it can be used with “water based, silicone or hybrid lubes” and they don’t say “Hey sure! It should be fine with oil!” like they do in all these other answers. “Should” be! SMH.

Customer asking if oil-based lubes can be used with Doc Johnson products, particularly the crystal jellies. Doc rep says: "Our UR3 pleasure items can only be used with water based lubes. All of our items made of PVC can be used with just about any lube you want". Way to dodge the actual question!

Customer asks: "will oil based lube degrade phthalate-free PVC toys? I'm not talking about if it's safe for humans, but only if it negatively affects the toy itself (resistance, durability). The Doc Rep answers with a mere: "Should be just fine". SHOULD BE.

Oh and yeah. Dishwasher safe. They never tell you to turn off the heat drying. I’ve always been under the assumption that heat is bad for these unstable materials. Given that the rep(s) don’t even acknowledge that oil is bad for their non-silicone materials, I don’t trust these recommendations, either, and neither should anyone else.

Customer asks: Is the crystal jellies classic dongs dishwasher safe? and Doc Rep says: "Oh yes. you can put them in the dishwasher but use the top rack".

customer asks: How do I clean / disinfect a Softee dont? (PVC) and Doc rep says: " warm water and liquid soap work great. You can even try the top rack of you dishwasher" (typo theirs) (and yes, they say "try" without giving any qualifiers on avoiding heat)

You know, I really liked the Truskyn line. I’ve assured others that Doc Johnson silicone IS silicone. I’ve said that while I don’t love their immense offerings of porous sex toys and I fucking hate their sil-a-gel bullshit, that they weren’t as bad as some of the other big companies. I don’t know, now. I just don’t know. Their responses when someone questions them are really fucking lovely: 

customer says: hello. I've been reading a lot about PVC and the safety factor of its use in sex toys. Since you supposedly do not use phthalates in the Titan men rumpy butt plug may I ask which plasticizer is used? and Doc rep replies: "All of our material that we use has been deteremind to be body safe. Oh....and we do not give out proprietary information. And...I have learned not to believe everything I read online"

Customer asks: Why do the silagel products always smell extremely abhorrent? Doc Rep repeats the same explanation about sil-a-gel as above, but says first "So...sil-a-gel isn't a material and doesn't smell" LIE!

“Sil-a-gel isn’t a material and doesn’t smell”



Please, don’t buy sil-a-gel-added products. Just don’t do it. This may mean you have to avoid Doc Johnson as a brand if you do not want to spend the money on silicone sex toys.

Is your glass sex toy safe? Image shows an array of glass sex toys on a teal backgroundEverybody and their brother claims to be creating/selling high quality glass sex toys; they may tout brand names like Pyrex or toss out the term “borosilicate” as if those words automatically mean quality anymore. When we know how shady many sex toy companies can be and how they can say whatever they want about their product without the need for truth in advertising, people naturally get skeptical regarding the true safety of glass sex toys. I’m always trying to find new ways of testing sex toys at home for quality, material, and relative safety. Since one of the few things I could do is burning to see if it’s silicone or not, I never thought I’d be able to test a glass sex toy at home until Crystal Delights talked about using a polariscope on some glass pieces which shows stress in glass. I figured out how to run the test at home, cheaply, and then proceeded to spend more than a few dollars buying various brands to test. I tested them all for glass quality and lead content  – I have no way of testing for Cadmium or other harmful heavy metals, though. I have always received questions about the relative safety of inexpensive glass sex toys and I can finally give you some more in-depth answers. I suspect we won’t stop with this post; I’ve already talked to Crystal Delights years ago and I plan to present you with a more in-depth chat with the people behind Fucking Sculptures, soon.

Please note: This piece is to inform and educate, not scare you. If you are worried about the glass sex toys you own after reading this, please contact me. Send me a link, send me photos, etc. I’ll help you determine if you need to toss it or just baby it.

Pyrex Means Nothing

You probably associate the name Pyrex with tough glass – glass that can stand up to a drop, that can be boiled, etc. On the boiling front, you’re right – borosilicate glass can be boiled or can be the vessel for boiling. But Pyrex just isn’t what it used to be anymore – namely it used to be well-made borosilicate and now it’s soda-lime.  Sometime in the 1990s Corning and their Pyrex name were bought out by a Chinese company called World Kitchen. Since then, Pyrex items just aren’t as tough. I ran the glass test on some Pyrex branded items I own – the new Pyrex measuring cups showed rainbows in the parts. The lid from my 1950s CorningWare casserole dish was completely clear on both the polariscope and polarimeter. A lab flask from the 60s was also showing clear on both tests. So when you see glass companies bragging about how they use Pyrex glass? They’re full of shit. Pyrex isn’t a type of glass, it’s a brand and it is no better or worse as a name brand than anything generic. If you want glass brand names that mean something look for people talking about Simex or Schott glass, which are used for medical purposes. Plus, if the glass isn’t annealed then nothing matters. I’ve seen a lot of cheap glass sex toys boasting “Pyrex” and they’re not annealed. Most of these same sex toys that use the term “Pyrex” also say “borosilicate”. Since Pyrex is no longer borosilicate this presents a bit of Pinocchio situation. So what are they really? They may very well be borosilicate glass, which is fine but just saying that doesn’t really make it any better than soda lime glass that is annealed – soda-lime is used by Fucking Sculptures, Steele Malone, Standard Glass and Simply Blown, to name a few. Even when annealed though you can’t plunge a soda-lime glass dildo into boiling water. But annealing does strengthen glass and make it able to withstand some abuse. My Fucking Sculptures soda-lime glass dildo may not be able to withstand boiling water but it definitely is hardy and break-resistant because FS makes their pieces carefully and properly. The cheap “Pyrex” now made in China hasn’t been made carefully; my newer measuring cups have all chipped on the lip/spout.

What Annealing Means (and doesn’t)

I talked to a lot of glass experts when researching this and I could include information from many people here. Some have said that it’s nearly impossible to anneal away all stress in thick glass sex toys; some disagree. Some “internet experts” have gotten the terms annealing and tempering confused; you probably wouldn’t find a tempered glass dildo.  First, here’s some information from Maria at Fucking Sculptures:

It is both theoretically and actually impossible to remove all stress from any glass, and especially so with objects that vary in thickness, shape, and color. Some stress actually strengthens glass, that extreme being known as “tempering” (also from metallurgy) or quick cooling, which is done to car side windows (not windshields!) and some drinkware. It makes them VERY hard to break up to a certain point way beyond that of annealed glass, but at which point they break into a zillion pieces. Do note that as stressed out as they are, car windows and drinkware never break themselves! Someone has to do it for them. So, having said all that, yes, our dildos do have some stress. We do anneal them in a longer cycle than most anything else made in our studio, because they are relatively thick. We anneal them in the upper part of our oven, which provides more evenly controlled heat. We also know that having some stress makes them stronger, having dropped them on various floors, even sometimes concrete won’t break them. There are other issues going on, too. Hard or soft, the skilled and careful glassmaker has to keep whatever object is being made fairly evenly hot throughout the sculpting process, thus taking a lot of the stress out of the glass before it even reaches the cooling oven. Design plays a part, too. That butt-plug ring you mention should never have existed in the first place, and more subtle things are prone to break as well – abrupt changes in thickness or angle can be interesting features in metal, for instance, but doomed in glass. Factory production of course is riddled with risks- harried or unskilled employees, quotas, deadlines, budgets- all of which increase chances for error, or worse. We avoid all that by having 2 people (sometimes a third) make everything.

Next, I want to share with you what Standard Glass told me:
Looking for strain with a polariscope is not just as simple as rainbow or no rainbow.  Yes, totally clear is a good sign.  But there are varying levels and intensities of coloration, and reading them is something that takes training.  Strain in glass doesn’t always make it weak, it can also make it strong.  Think about tempered glass, like is used in skyscraper windows.  Tempered glass has a controlled pattern of stress put into it during manufacturing.  It is very flexible and durable, and takes immense amounts of bending from wind, earthquakes, etc.  Regular, annealed sheet glass would surely snap, but the tempered glass doesn’t.  However, once the tempered glass reaches its limits, it blows up into little square chunks like auto glass does.

This would be bad for a sex toy, but is an example of how complicated strain is.  The junk import “pyrex” toys are just formed at a torch and likely allowed to cool on a tabletop.  Maybe they go into a kiln, but I’ll bet not.  This is not good strain in glass, and it’s not safe.  I’m not expert enough to properly read the stress in the images you sent, but my basic understanding is that the tighter/brighter the rainbows are, the higher the stress levels are.  The mellow brown/purple haze is likely safe for use.  You might try going to your local university and seeing if they have a scientific glassblowing lab in the chemistry department somewhere.  Down there, there will be someone who knows quite a bit about polariscopes and glass.  They will likely also have a much fancier polariscope with graded dials, one that can let the user rate strain in ranges and give a better idea of its stability.

The toys we produce at Standard Glass are of soda lime glass, not pyrex, and if we put our toys on the tabletop after making them, they would blow up before they’re cool.  Everything we make goes through a computer controlled cooling process in a large, well calibrated, custom kiln.  We have made clear toys and both polariscope tested them (polariscope only works on clear glass), and also test them by breaking/sawing them into pieces.  Glass with stress breaks/cuts differently than well annealed glass. 

Color is also a source of stress.  Making colored glass changes the physical attributes of the glass, and so the color formula needs to be chemically tweaked so the final result “fits” with the clear glass you’re using.  At our shop, our color is made in New Zealand, is tailor made for our clear glass and our process, and is tested at their factory.  We also test each batch of color with our product/process here at the shop before we use it.  In China or any other glass shops, there’s no telling what’s happening.  Hopefully they’re being thorough, but that’s why it’s best to stick with long time, tested toy manufacturers. When I see a Chinese glass dil with two or three colors in it for $17 retail, I definitely wouldn’t recommend putting it inside anyone.  Stick with older, more trusted brands.  Stay domestic.  Pay a fair price.

What’s the Big Deal?

Cheaply made glass sex toys are still unlikely to break while they are inside of you. When a cheap toy has a stress point (thin necks, like butt plugs or handles) there is a greater chance that it will break at this spot. As you’ll read below I’ve come across one instance of a glass sex toy breaking while inside someone’s body.

What is more likely to happen is that your glass sex toy will simply break/crack easily even with great care. As it gets used and handled over time the stress inside the glass gets worse until one day it falls off your bed onto your carpeted floor and breaks in half. Or a chip forms on the base of your plug. As long as you thoroughly examine your glass toy before every single use and after every single time you clean it I don’t feel that there is a huge risk of bodily harm in most cases.  I’ve heard from many people that cheap glass sex toys have arrived to them already broken, scratched, etc.

Sadly, as is the case with porous materials versus body-safe materials, there will always be a large number of people unwilling or unable to buy a properly made glass sex toy. When an improperly made glass sex toy can be had for under $20 while an annealed, hand-made glass toy can cost hundreds of dollars the choice to take the risk is understandable. Amazon is, naturally, appealing but take a look at what happened when I tried to order a few “name brand” pieces from Amazon as part of my testing phase.

Bottom line: cheap glass sex toys will need to be replaced; high quality glass sex toys won’t. A cheap glass sex toy may break easily; a high quality glass dildo won’t.

How to Test Your Own Glass Sex Toys

The test only works on clear or light-colored glass. Dark glass won’t show you much, if anything. Pastel blue, pink, lavender and maybe glass with small shots of color running through will all work well in the test. All you need is a computer monitor and a circular polarizing lens – I used this exact one in part because it was a lot bigger than my existing camera lens 1 (my c-polarizing lens that I use on my camera is 40-some mm, fairly small) and in part because it was cheap. Since I wanted to take photos that showed both the view from behind the lens and naked glass, I didn’t want to attach the polarizing filter to my camera lens. I also used a small light tent box to make sure that what I was seeing wasn’t a reflection of other things. It seemed to work best when the room was dark with no overhead light. It also worked best to have a totally blank, bright white screen, so I used this webpage and F11.

Depending on which way you look through the lens you are creating either a polarimeter or a polariscope. The polarimeter shows color where there is minor to moderate stress, but it requires a degree to figure it out. The best answer I could get was from Glass Alchemy who said that “totally clear is best, but those showing gold and indigo are still relatively strong and shouldn’t be a problem”. You will only see the gold and indigo if you’re using it as a polarimeter. How to tell if you’ve got -meter or -scope? When you hold the lens and rotate it, the -scope side should at some point black out the monitor, as shown in my photos below. Now according to Glass Alchemy and Fucking Sculptures, showing some stress isn’t bad. According to Crystal Delights, showing any stress is bad. If I test items that I know are made to withstand drastic conditions (vintage Corningware Pyrex casserole lid and a lab flask) they show zero stress. Personally, with the small market share of glass sex toys that have been annealed being what it is, I’ll still recommend some brands that show *some* stress versus a lot of stress just because the list of “no stress” perfect glass sex toys is woefully small. I know you need choice

How to Evaluate the Results

This is pretty much the one time in life where rainbows are bad. It doesn’t matter which side of the filter you look through, if the piece is mass-produced in China with no tempering or annealing in any way then you will see rainbows. This means the piece is holding on to a lot of stress at various points and can break easily. It can be fine for a few years and then one day break easily – Sunny Megatron described this to me with a dildo that was great for a couple of years and then one day it took a light fall 2 feet from the bed to the carpeted floor and it broke.

Conversely, a properly annealed glass sex toy could be dropped from a few feet onto a hard surface and probably suffer no damage. Maria from Fucking Sculptures has said that they’ve dropped their annealed pieces on a concrete floor and they didn’t break. Standard Glass has said the same.


What you ideally want is a glass sex toy that has been annealed – and it’s highly unlikely that the mass produced China products have been. Annealing means that after the hot glass piece is done being created, it is put into an oven which is brought up to a certain high temperature, over 1000 degrees Fahrenheit, and then slowly cooled at a precise rate. This takes two things the China plants usually don’t have – time and money. In my testing I only ran across 2 mass produced brands that had pieces that weren’t filled with rainbows.


Are Colored Glass Sex Toys Safe? Is Painted Glass Safe?

I’ve seen some shady stuff in my searches, like CalExotics dildos with decals painted on and Pipedream dildos with a weird irridescent glaze to them. I’ve also wondered about the colored glass bumps, dots and swirls we often see added to the design. According to Ryan at Luscious Playthings: “There are “lusters” that can be applied to the surface of glass and then fired on in the kiln, sort of like a glaze, but they’re highly toxic. As for bumps or texture being added to the surface, as long as it’s melted in good it should pose no threat.” Nearly all glass artists are using colored glass – they get pre-colored glass rods to create the lines, swirls and flowers/mushrooms or “frit” which is crushed colored glass that can be used inside the clear or rolled onto the outside (the latter is how Fucking Sculptures does it).

Another interesting tale which involves, naturally, Pipedream’s Icicles line. Jane told us about someone who boiled a red Icicles dildo and the water turned red! Whatever was going on here, they weren’t using red glass. It sounds like they were using some sort of luster or paint. Not safe! I tried boiling some colored dildos to see if there would be any bleeding in the water and I didn’t detect anything. Someone else commented here about the color flaking off during boiling of their Pipedream Icicles.

And what about metallic coatings? How hardy and body-safe are they? Unfortunately I don’t know. It would take lab tests to find out the material they are using combined with extensive wear tests to see if it rubs off like the metallic coating on Lelo items.

Another question has been about leaded glass – is the cheap stuff riddled with lead? Turns out, nope. Not a single item in my possession tested positive for lead. Only one glass thing in my house did test for lead, but that was a decorative ornament. I used the 3M Lead Check swabs.

Glass Sex Toys to Avoid

At this point, I’m reluctant to tell you to avoid certain brands. Sure, if I had my way about it I’d tell you to avoid Pipedream and retailer-branded glass, and of course everything from Amazon. They’re not going to be annealed, ever. I don’t feel, nor does anyone else I’ve spoken to, that most of these designs will break/snap while inside your body. I don’t see you exerting enough force on the object, nor would the temperature change from cold to internal body temp be enough to stress it to breaking.

There is one major design I cannot recommend: The style with a pull-ring at the end. If you see this style made by the cheaper companies, AVOID IT. The following story is true:

An employee of Nitecap Megastore on Staten Island shared the photo with me. She purchased this to use on her partner, after finally working through his skepticism on trying prostate stimulation. The piece in question had been handled with care on her end and this happened the first time they used it – the pull ring broke while it was in his ass. “Luckily the plug wasn’t even fully situated in his ass yet so he was able to contract his muscles and push the piece out on his own”, she told me. I’ve spoken many times about the amazing “vacuum” nature of the butt; if a large salami or bottle of pancake syrup can get sucked up and require a doctors care for removal, I’m sure you can imagine how easily that incident with the broken glass piece could have been a serious accident. The lacerations he would have sustained internally could have been life-threatening.


Other tips for deciding if a glass piece from an artist is truly their own, or not: check to see if the design(s) are common. One of the most common designs was (originally? I think?) the Don Wands Bent Graduate. SSA Glass called it the Amethyst. I’ve seen it all over Amazon and I’ve even seen it in the small Etsy shops where they claim to hand-make all their own glass to the highest of standards. Could they just be making that design because it’s popular, and it’s still a quality handmade piece? Sure, absolutely. But when I look through their shop and see generic designs that feel familiar, I move on.

One company I will tell you to avoid is The Glass Dildo Shop aka A Tough of Glass, a UK seller. The company owner is a lying sack of crap, so there’s that, but their site has this ridiculous scare-tactic post warning you about low-quality glass sex toys, how easily they break and even show a photo of a shattered glass plug to scare you further. The irony here is that their pieces are the exact things they warn you against. In the height of the drama as we uncovered more info about The Glass Dildo Shop someone sent me one of the dildos they received for review and it didn’t pass the polariscope test. Rainbows galore! Their post which talks about “regular window glass” is an infuriating piece of bullshit, especially given their lies. It’s not about the glass, it’s about the annealing!! They talk about second-hand glass dildos leading you to “contract something nasty”, and while used products are certainly a possibility in some crappy markets, glass is truly non-porous and very easy to sanitize.  I fucking hate this company and would like to see them disappear from the internet for good, along with the owner David Mattocks.

Glass Sex Toy Brands I Endorse

When I was gathering up glass from various companies, and in many cases speaking to the company owners/glass blowers, it became clear on who you can trust to give you a high-quality product.

Crystal Delights: They inspired me to write this piece and do the testing; I couldn’t get the polariscope they used, so I fashioned my own. I fully trust every product from Crystal Delights. I even tested an item from them myself and it was perfectly clear with no visible stress. You can buy direct from CD, or purchase select pieces at SheVibe.

Fucking Sculptures: I couldn’t test their pieces with the polariscope because of the colored glass they use, but I’ve dropped a piece (no damage) and have talked extensively with Maria. I’ve seen videos of their work and I fully trust that every product from Fucking Sculptures is annealed and made properly. You can also buy these at SheVibe.

Luscious Playthings: They currently sell on Etsy, and used to have a few styles that were sold by GoodVibrations under a different name. The piece they sent me shows as nearly clear in my tests, I only notice a bit of gold/indigo when I turn the product certain ways – however the piece they sent me is also much larger/thicker than the other items I’ve tested. It has been noted that with the thick pieces it would be pretty damn difficult to get rid of all stress from annealing. I’d rate their glass highly. While their stuff isn’t as fancy as Crystal Delights or Fucking Sculptures, you’ll find a lot of moderately-priced interesting designs that work well. They have a lot of glass butt plugs, and a really interesting handled dildo (which they sent me to try out) which I quite enjoyed – the shaped and handle were great but I don’t like textured bumps as a personal preference. I tried not to let the bumps affect how I feel about their piece overall. You know I like dildos with a long handle and curve for easier use and theirs certainly lived up to my standards. I would definitely recommend Luscious Playthings as a safe company with great products.

Glass by Woozy: They also sell on Etsy. I purchased a really small, clear piece from them just to test and it passed the annealing test. A number of bloggers have reviewed their items and have always been happy with the end result.

Standard Glass: They only sell to particular stores; Babeland and Smitten Kitten being a few. They sent me a totally clear version of their product to include in my testing and it showed absolutely no signs of stress. It’s well made and the colored versions are beautiful.

Ttamage: Another Etsy seller; also has seen a good number of blogger reviews. I haven’t tested anything from them but I have spoken to the owner/blower when I’ve done research and he knows his stuff. I would recommend them.

Simply Blown, Steele Malone, and Phallix Glass are also brands that I’ve heard good things about. Phallix is hard to find, and so far I’ve only seen it at Holistic Wisdom.

Glass Sex Toy Brands and My Testing

The following items I purchased or received for testing purposes did not pass – results were obvious with a lot of rainbow action: Lovehoney brand, 50 Shades of Grey line, 2 knock-off dildos from Amazon, Spartacus Blown, Pipedream Icicles, Edenfantasys brand, A Touch of Glass/ theglassdildoshop.com brand.

The following items showed extremely little or zero stress: Crystal Delights, Standard Glass, Glass by Woozy. These items are as perfect as my vintage Pyrex/Corningware lid and my lab flask.

The following showed indigo/gold (low-to-moderate) stress: Luscious Playthings, Jopen Key Comet G Wand, Glas Chili Pepper (this one showed the most indigo), NS Novelties Heart Wand, Sinclair Institute.

A few miscellaneous things I wanted to note: as part of my test I was going to send an already-photographed rainbow-y dildo over to Crystal Delights and have them anneal it. Yes, they can anneal an already-made toy, and have done so on their own to show that it wasn’t the glass quality giving a bad polarimeter reading, it was the lack of annealing. However, the research and massive undertaking of this project meant that I first started researching and gathering product as early as August of 2015 and only now in almost-June of 2016 am I publishing this piece. I feared that if I put this off any longer I would never get this beast of a post published.

Also in the vein of “I need to get this published, it is looming over me and stressing me out” my photos aren’t as awesome as I wanted them to be. I guess it only really matters that I am showing the differences, but still. My apologies here.  When I locate the larger lens filter I’ll re-shoot the images here.



  1. By the time I was ready to click publish I realized I didn’t have nearly enough photos – and suddenly I couldn’t find my large polarizing lens. Squinting to see through my little 40mm one was pure hell

It was September of  2013 when we first met the cast of the Jar of Melted Sex Toys aka Jar of Horrors…..

When I filled the jar May of 2013, I filled it to the lid. After seeing the Smitten Kitten original jar (which you’ll see in the video here) I knew that I could put these old sex toy bits to good use. The blue Blossom Sleeve and the clear pieces are TPR; the purple bit is from an old tentacle dildo from ZetaPaws and it was PVC probably with phthalates. I’m not sure anymore what the orange things are made of – I’d assumed TPR but they’re not deflating as much (probably because they had less fillers and softeners) so your guess is as good as mine. The sex toys had a bit of a head-start with breaking down, as they had been in storage for awhile. The Blossom Sleeve was the last thing to be shoved in. It only took three months though to have a small puddle of oil and overall content shrinkage of about and inch-ish.

wholejar meltingglitter

In November of 2013 I noticed that the liquid in the bottom of the jar seemed to have doubled. The purple thing had drifted down into the abyss a little, while also losing a bit of its mass. 


Fast-forward a year, to November 2014. By this time I’d already unveiled my boring Jar of Silicone in February (which is still unchanged, btw…no reactions).The purple bit which was once up to the Ball logo is now down at the bottom. Overall, the contents had fallen even further, leaving more empty space.

MeltedJarNov14 MeltedJarNov14pt2

In June of 2015 I unpacked my jars a few months after our move. Because the Jar of Horrors ended up on its side for a few months the contents really shifted. It was then that I realized that the clear, glitter-filled TPR rabbit vibe material seemed to be a glacier-like mass of goo, probably about the consistency of half-set jello, maybe? It was capable of looking like a puddle of oil or just a mass of ice. It only took a few hours of the jar being uprighted to see the glacier of goo shift and change. To be honest I was pretty fascinated.


Today I decided to take more pictures as I come up on another year since the last time we checked it. The jar took a trip to Woodhull’s Sexual Freedom Summit in August of 2015 so that people could see it in person, but I’d pretty much ignored the jar since then.

JarMay16-Whole JarMay16-4

JarMay16-1 JarMay16-2


I don’t think that what appears to be oil filling nearly half the jar is actually a liquid. I think it’s a combination of this clear TPR which has deflated and transformed, plus all the oil. Let’s take another look though (sorry about the noise – it’s windy today!)


These materials, toxic or not, are all porous and “chemically unstable”. The materials have a high amount of plasticizers (plastic softener) which is sometimes phthalates, sometimes mineral oil, sometimes….who knows what. There is oil in all of these materials; you can tell this when they start to first decompose and “sweat” and feel greasy. I believe that for some toys, even if stored alone and in proper conditions, they won’t break down very quickly. All it takes is some stop-touching-me contact though and suddenly it’s a horse of a different color – it’s like a snowball effect. They touch and the oils from each somehow start a reaction in the other toy. This multiplies and continues; the more oil, the more touching, the more it all deforms and deflates and oozes. The liquid in the jar is heavy and thick like mineral oil, maybe even a little thicker than that. It’s fascinating in a science-geek way. It’s gross because this is how these crappy materials behave, this is how unstable they are and thousands upon thousands of people are using them. They don’t know because they assume that if these materials are being sold to us, then they must be safe. They don’t start researching online until something bad happens – until their sex toy deforms in their drawer, grows mold (which shows up at first as black dots) or burns their genitals.

And lest you think that this only happens in certain conditions, like a jar, I can point you to other images. Like this time that a reviewer left a TPR masturbation sleeve on the PVC head of the Doxy Wand for an extended period of time (past his use of it).

SilicaGelSilicone. It’s the “gold standard” material of sex toys for most, and it’s also the material we’re the most leery about. You see, for years we were tricked. For years we were sold silicone sex toys that were anything but, because there are no regulations and they can tell us it’s made of fucking unicorn poop and wouldn’t get into trouble. So we started taking a lighter to it and calling it out when we’d find something that didn’t deliver on its claims. The industry seems to have gotten a lot better with silicone usually being silicone, and us seeing more affordable silicone options.

But we still have a lot of confusion. I recently cleared up the whole Sil-a-gel debate (additive; not material) but I keep getting asked about Silicon and “Medical Grade Silica Gel”. Take a guess at where we’ve heard the latter. Come on, I’ll give you three guesses. Yep, AMAZON. Ebay. AliExpress. So I decided I had no choice but spend some money and see what is what.

Is Medical Grade Silica Gel Even a Thing??

The term “medical grade silica gel” is coming up so often on the sites I don’t recommend you shop at for a major reason: I suspect it’s a language barrier thing. When you see it you can assume that the listing is made by one of those companies that is selling knock-offs and cheap crappy toys straight from the China plant they were made in. Most of the items listed on Amazon as “medical grade silica gel” shipped from China; it was hard for me to find some that were on Prime (because I’m cheap AND impatient). The other thing I notice: On most listings that say “medical grade silica gel” they ALSO say “medical grade silicone” somewhere in there, or just silicone. The only thing I can find for silica gel is the desiccant stuff; it’s found in hard pellets. It’s related to silicon. It’s NOT a sex toy material and should never be trusted. I think that if you see something listed as this, run the other direction. You have a 2 out of 3 chance that it’s not silicone.

The first item I picked, I picked because it obviously wasn’t silicone – the material is crystal clear. This rabbit is weird and cheap and who would want soft spines?? Anyway, what’s interesting is now the listing mentions nothing of medical grade silica gel, or silicone. You can see in the screencaps below that it used to. It’s now listed properly as TPE.  It’s a good thing I got screencaps; I did that initially because I assumed that at some point they would stop selling the item. I didn’t realize some would actually change the material listing.

SilicaGel6 SilicaGel7

The second item I chose because it looked like it *could* be silicone, and it was cheap and didn’t come directly from China. On Amazon, it’s called  Utimi brand – the rabbit up above did come in branded packaging that said Utimi, but this blue thing came branded as Shaki. Hey, it’s not the first time they called it one brand on Amazon and I got another. This Utimi brand also wasn’t the only brand I tried to purchase – I tried to purchase two others of a different brand, from a different seller, but they both were canceled. The listing showed something like “12 in stock” but then shortly after ordering it was canceled. They wrote to tell me they’re sorry, it’s out of stock. And never coming back in. And here’s a refund. It felt kinda shady, if I’m honest. Oh have I mentioned that my user profile on Amazon links to my blog? Is that relevant? hmmm

SilicaGel3 SilicaGel4

And the third item is a little bunion-protector/toe separator. I’ve seen these and similar foot things on the site just as silicone, or as the silica gel. I actually purchased something similar a few months back, looking for a cushioning heel cup. I thought the material felt identical to the Tenga Eggs, but since I wanted to return the item I chose not to burn it. There are a ton of these on the market, most are listed incorrectly in terms of material, and the material looked a lot different than the rabbit. Since the “frost” sorta reminds me of the white O2 layer on some Tantus toys, I thought there actually was a chance it could be super-soft silicone.

SilicaGel2 SilicaGel1

The burn verdict: The crystal clear rabbit was obviously not silicone, but we knew that just by looking. The material lit up easily and burned like an oil lamp, the material merely melting/deforming. No ash. The blue thing behaved exactly like silicone – a scorch mark I wiped away, ash when it finally caught a bit of a burn, not much material destruction. The toe thing? Behaved just like the crystal clear rabbit – it burned bright, hot and easily with obvious deforming/melting and no ash.


The use of silicon vs silicone doesn’t really seem to be a cultural thing or a language-barrier thing; I’ve seen all variety of people misusing this term. It becomes even more confusing then, and makes us side-eye real hard, when a manufacturer rep uses that term on social media.

Silicon (Si) is not silicone. Not even close. It does eventually make up another awesome sex toy material though – glass. Guess where else it’s naturally found? Quartz. This isn’t something that eventually makes up your average soft dildo, folks. Whether it’s a typo or just a lack of understanding of science and the elemental chart, the use is too common and should be corrected whenever you see it. Does seeing it being used mean that they may be lying? I’m not sure. It’s too easy to mix up the two when you are not paying attention to basic material information.


Silicone can be a liquid or a solid. People sometimes say “silicone rubber” and they don’t mean they think it’s a blend, they’re saying it to convey that it is a rubber-like version of a silicone product. I’ve also seen some say “silicone elastomer” to convey the same meaning, but without the negative connotations of the word “rubber” (they don’t realize it’s redundant to us, and makes us wary). It can be super soft and squishy, or really firm. Silicone can hold onto strong odors1. It won’t melt when it touches other cured silicone products. It’s essentially non-porous and bacteria, mold, and other fungi won’t breed and make homes in the tiny pores. When you burn it, if it catches, you’ll see a light grey ash. It can be cheap or expensive.

But please, don’t ever call it ‘Silicon’ and run from places that say ‘Medical grade silica gel’.

  1. yes, you can get rid of the odors, yes I’ll write about that down the line
