What Types of Glass are Glass Sex Toys Made from?

Most glass sex toys don’t look all too different from each other structurally, and if you’re pretty clueless when it comes to glass (like I was a few hours ago), then you wouldn’t know that there is a heap of differently processes that come into effect when making glass sex toys!  Just like the glass in your window isn’t the same as what’s in cutlery cupboard, they’re entirely different forms of glass with entirely different processes that effect their durability, and the same goes for our glass sex toys!

The first step you can take to understand what glass your toy is made of, is to learn the correct terminology! Because you’re going to see this language thrown around anywhere glass sex toys are mentioned – online and in person - and we want you to be as informed as we are, let’s learn the lingo!

Soda Lime Glass

Accounting for the majority of all manufactured glass production, Soda-Lime glass is the most common type of glass around, and is often found in non-sex toy forms, such as windows and bottles. Obviously, since we’ve all seen a bottle smash, this isn’t your strongest glass! 

Borosilicate Glass 

Now here’s the tough stuff! Engineered to hold-up through rougher conditions, both thermal and chemical, borosilicate is a common glass used for sex-toys. It’s also commonly used in cookware (Pyrex was made borosilicate, before it changed manufacturers) and lab equipment, due to its last nature. 


An essential process when engineering tougher glasses, the process of annealing is to minimise the risk of internal stress in the glass formations, and to relieve any residual stress’s from during manufacture. How they do this is by slowly and meticulously cooling down the glass, in controlled processes. This is the golden and safest standard when it comes to manufacturing glass sex toys! 


Now this is where things get tricky, because stress isn’t always a bad thing! Some stress points in glass can make those parts weaker and more susceptible to breakage, but on the other token, there are some instances where glass stress can make things stronger. However, the main thing with glass sex toys is that they are structurally sound.

FUN FACT: Some makers say it’s impossible to have a piece of glass that’s 100% free of stress, while others say it is. There is also a certain amount you can have while being safe to use.

So, We Know What Glass Sex Toys Are Made From…. What Now?

Now we need to understand what’s safest for us and our bodies. 

First, understand that although borosilicate is the stronger glass, a borosilicate glass toy is NOT automatically better than a soda lime glass toy. Why? As with anything, the quality of your glass toy will come down to the processes implemented during its manufacturing. 

As a general guide for the quality of your glass sex toys:


     1. A well-made, annealed, borosilicate toy is the BEST!

     2. A well-made, annealed, soda lime toy is also great!

     3. An annealed toy can still be bad if it’s crafted poorly. 

Now, I’m a firm believer that sex toys don’t need to be super expensive to be pleasurable, however when it comes glass, you certainly do pay for quality, and with that, safety. I recommend to keep cautious of any cheaper branded glass toys, to meet dead-lines cheaper glass sex toys often haven’t been manufactured with caution and care you would expect – now this isn’t to say that just because they’re more affordable, they’re necessarily bad, but do your research before you invest!

Final Thoughts

So, we have discovered that the majority of well-made glass sex toys, are typically borosilicate and then annealed for maximum structural support. We hope this little breakdown helps you understand what to look for in your glass sex toys!
