What is Borosilicate Glass

Written by Selena Kemp

Borosilicate glass is a type of glass that contains boron trioxide. This additive allows for a very low coefficient of thermal expansion which means the glass will not crack under extreme temperature 🌡️ changes like regular glass. Its durability makes it the glass of choice when quality glass is needed. Such as in high-end restaurants, laboratories & wineries 🍷.

Just like regular glass, Borosilicate glass is completely non-toxic.

In the past companies like Pyrex used it as a safe material to make heat-resistant glass jugs, glass bottles, & cookware.

So is Borosilicate glass unbreakable? No, it is known for its low thermal expansion & high resistance to thermal & chemical stress, but it can still break or crack if it is exposed to excessive force or extreme temperatures 🥵.

What are the Disadvantages of Borosilicate glass?

Cost | Borosilicate glass is more expensive 💰 than other types of glass, making it less suitable for cost-sensitive applications.
Brittleness | While Borosilicate glass is relatively strong, it can be relatively brittle & can break or shatter under stress or impact, just like any glass.

Borosilicate glass is lead & BPA-free, making it perfectly safe for use as drinking glasses.

It also provides excellent clarity & visual quality making Borosilicate glass the perfect choice when selecting glass products to brand with your logo.
