What is Borosilicate Glass?
Borosilicate glass is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion. This means it will not crack under extreme temperature changes like regular glass. Its durability has made it the glass of choice for high-end restaurants, laboratories and wineries.
Borosilicate glass is made up of about 15% boron trioxide, which is that magical ingredient that completely changes the behavior of glass and makes it thermal shock resistant. This allows the glass to resist extreme changes in temperature and is measured by the “Coefficient of Thermal Expansion,” the rate at which the glass expands when it is exposed to heat. Thanks to this, borosilicate glass has the ability to go straight from a freezer to an oven rack without cracking.
The benefits of borosilicate glass
Completely safe and nontoxic
Resistant to thermal shock
Extremely durable and shatterproof
Eases the burden on the environment
What borosilicate glass is used for
Because of its resistance to thermal shock, borosilicate glass is often used in settings that require high heat or extreme temperature fluctuations. In fact, its maximum thermal shock range is about 340 degrees fahrenheit. This makes it great for laboratories, ovenware and other kitchen and cooking applications, industrial settings, and chemistry labs.
