Are glass sex toys safe? It’s a question I’ve heard on many occasions. Despite my long love affair with glass sex toys and many reviews for glass dildos here at the Cara Sutra sex blog, I still come across people who are shocked to learn that glass is a material used to make sex toys. Today I want to explore the misunderstood realm of glass adult products, dispelling myths, revealing the facts behind the specific type of glass to make these products, and the dos and don’ts of self-pleasure safety with glass dildos.
Yes, glass sex toys exist and they’re safe to use
Yes! Glass sex toys not only most definitely exist, but they’re also often exquisitely beautiful; objet d’art. Whether in clear glass, colour-tinted or boasting internal splashes of colour or patterns, glass sex toys have an intrinsic allure. Their aesthetic beauty is only magnified when the light catches their sculpted contours and nodules.
Are they just quirky ornaments? Or can you actually use them?
You would be forgiven for thinking, after I’ve just waxed lyrical about their appearance, that glass sex toys aren’t for intimate or internal use at all. Perhaps glass dildos are just quirky ornaments to inspire eroticism in the boudoir, or as a talking point for a particularly brazen mantelpiece. But no, glass sex toys aren’t just gloriously beautiful to gaze upon, you can use them for internal, sexual stimulation too.
Aren’t glass dildos dangerous? Glass seems like such a fragile material!
It’s easy to see why people are surprised and even incredulous when they discover the existence of glass sex toys. We are taught from an early age to be careful with glass objects, that glass is a fragile material that splinters into sharp, dangerous shards when broken. Many of us have experienced minor injuries from mishandling broken glass. Therefore, learning that glass is not just a material used to make sex toys, but those sex toys are absolutely safe and viable for stimulating internal use, can be difficult to comprehend.
First of all, it’s imperative to understand that there is a marked difference between the fragile glass you imagine shattering and causing injury, and the glass material used to make internal-use sex toys such as glass dildos. Top-quality glass adult toys from reputable sex toy manufacturers are usually solid glass, rather than hollow, for a start. In addition to the solid design, the glass used is borosilicate glass – yes, the thick, sturdy, resilient, heat/cold/fracture-resistant glass used to make ovenproof bakeware such as Pyrex.
My favourite glass sex toys
I’m so excited to share a list of my favourite ever glass sex toys with you. These are the most stimulating ones I’ve experienced, over the 15+ years I’ve been reviewing sex toys. Although I usually enjoy glass dildos vaginally, depending on the style they can be enjoyed anally, too. Sex toys need a flared base or widened, defined handle if you are to use them safely for anal pleasure. For anal play, lubricant is also a must.
Loving Joy Spectrum Nubby Textured Glass Dildo: This chunky, nobbly-bobbly dildo is an absolute gasping-with-delight dream for stimulation lovers like me. It’s also a great value, budget-friendly price. The rounded end makes a comfortable but also easy to keep hold of handle.
Tracey Cox Supersex Glass Dildos Set (buy here in the UK): A true value-for-money set from a reputable brand and trustworthy sex shop, this set comprises not just one but two glorious glass dildos to enjoy. The clear, curved style reminds me of njoy’s fun wand, while the girthy pink option provides rigidly straight but highly stimulating intensity.
Glacier Glass Pink Tentacle Dildo: Another erotic joy when it comes to internal stimulation, this glass dildo adds in some kinky tentacle fantasy for good measure.
Glacier Glass Devil’s Tongue Dildo: Well, of course the devil’s tongue is a glass dildo… This gently pointed dream of an internal play glass sex toy offers a narrow and easy to insert tip, with all over texture to enjoy.
Icicles No 38 Glass Dildo with Leather Flogger: I so love a versatile sex toy, and this 2-in-1 combo of a ridged glass dildo which also forms the handle for a delightfully kinky flogger is one of the best I’ve ever had the pleasure to own and wield.
What’s different about the glass used to make glass sex toys?
Borosilicate glass, the type used to make both Pyrex ovenware and sex toys, is completely different to the fragile, thin glass used to make drinks glasses or Christmas baubles. Glass sex toys are therefore designed to be incredibly safe for external and internal sexually stimulating use, when used correctly.
The glass used to create sex toys is thick, solid and has a smooth, body-safe surface without any sharp nicks or detailing. In addition, borosilicate glass is designed to withstand significant temperature changes. It has a very high resistance to thermal shock due to its low coefficient of expansion. This means that it can better withstand rapid changes in temperature, whether very warm to very cold, or vice versa.
What about glass vibrators? How do they work?
Even after many years loving glass dildos, I was a little doubtful when I discovered glass vibrators. Vibrating glass doesn’t seem to be a good idea, especially anywhere near the nether regions – toughened borosilicate glass or otherwise. How do glass vibrators work? Are they also safe to use on and inside the body?
Although glass vibrators exist, they aren’t as common or easy to find as glass dildos and butt plugs. Due to the incredible integrity and resilience of borosilicate glass, not only are glass vibrators from reputable sex toy manufacturers safe to use, but the glass material is also a fantastic conductor for the vibrations. None of the powerful vibrations get trapped or muffled in the material; all that delicious vibrating pleasure is delivered exactly where you need it most.
Glass vibrators most often comprise of a central core inside which there is a vibrating motor that delivers vibrations to the outer thick & durable glass encasement, or a handle/base design within which the vibrating motor is located, delivering vibrating pleasure to the attached, solid insertable glass portion of the sex toy.
My three top choices when it comes to glass vibrators to try out are:
Bondara Glass Bullet Vibrator: A rechargeable, waterproof, 4.75-inch-length bullet vibe with 3 speeds & 7 patterns plus an eye-catching design.
Prisms Vibra-Glass Dual Ended Vibrator: Choose the silicone or the glass end for internal stim with this luxurious, rechargeable, IPX6 waterproof vibe with 3 speeds & 7 patterns. Comes with a velvet storage pouch.
Chrystalino Pluggy Glass Anal Vibrator: Small enough even for anal newbies, this glass anal vibe offers 10 vibration speeds & patterns and comes with a silicone suction cup for secure seated pleasure sessions. USB rechargeable & hassle-free, wireless operation with the included remote control.
Glass Sex Toy Safety: Dos & Don’ts
Do
- Use them slowly and gently, their rigidity can feel quite intense if you’re unused to the sensations
- Warm them up before use in a bowl of warm (not boiling) water if you’re not into the natural chill factor of glass
- Experiment with temperature play if you’re feeling brave enough, but always triple check the toy is a safe temperature before use
- Seek out glass sex toys from trusted adult product retailers and manufacturers for material safety reassurance & peace of mind during use
Don’t
- Drop from a height on to a hard floor (best not to drop them at all, if you can help it!)
- Use too roughly as you risk causing damage
- Use glass sex toys from questionable sources, websites or manufacturers
- Slather in lube then use in the shower or standing up, as you or the toy could slip, fall and risk injury/damage
Top Tips & Useful Information
You can use any sex lube you like with glass sex toys; they aren’t porous and the material won’t react or degrade no matter the type of lubricant you use. For more information about sex toy materials and the different types of sex lubes, check out my guide to sex toy materials and complete guide to sex lubes.
As mentioned above, when using lube with your glass sex toys make sure there’s no risk of it slipping and falling from a height on to a hard (or any) floor. I advise glass dildos & lube use while laying on something soft and safe, like your bed! Pop one of these fluidproof sheets underneath you if you’re worried about wet patches or staining your bed linen.
Remember that glass is a rigid, not flexible, material. Unlike flexible sex toy materials like silicone, glass sex toys will retain their unrelenting hardness when they enter your body. If you use a glass dildo with nodules, ridges or other textures, you will likely feel these more intensely than if they were on the surface of a different material sex toy. Go slowly, and ease the toy inside gently. Rough, vigorous play with glass dildos could lead to discomfort or even injury.
I recently wrote a helpful guide to temperature play in the bedroom, which is when you (or you and your partner) explore the erotic sensations provided by heat and/or cold. Glass sex toys are an effective and easy way to experiment with temperature play, as they can be warmed up or cooled down in a bowl of relevant temperature water before use. Never use boiling water, and don’t use a freshly frozen glass dildo – think what happens if you lick a frozen lamppost!
In Conclusion
Exploring the world of glass dildos can be an exciting and fulfilling journey, offering a unique blend of elegance, functionality, and pleasure. By prioritising safety – choosing high-quality, body-safe options, taking care to avoid knocks and damage to the toys, using good quality lube, and cleaning thoroughly after use – you can fully embrace the benefits of these versatile adult toys with confidence and peace of mind.
