What is High Temperature Glass Made Of?
High temperature glass, also known as borosilicate glass, can withstand extreme temperatures, making it an ideal material for laboratory equipment, cookware, and glassblowing. But what exactly is high temperature glass made of?
High temperature glass is composed of a mixture of silica and boron. Silica is a naturally occurring mineral that is found in sand, quartz, and other materials. It is widely used in the manufacturing of glass due to its ability to withstand high temperatures and resist chemical corrosion.
Boron, on the other hand, is a chemical element that is added to the glass mixture to lower its coefficient of thermal expansion. This means that the addition of boron prevents the glass from cracking or breaking when exposed to sudden changes in temperature.
The combination of silica and boron creates a glass that has a low thermal expansion rate and is highly resistant to thermal shock. High temperature glass can withstand temperatures as high as 450°C without cracking or breaking, making it ideal for use in laboratory equipment such as beakers, test tubes, and flasks.
High temperature glass is also commonly used in cookware, such as baking dishes and casserole dishes, due to its ability to withstand oven temperatures without breaking. It is also dishwasher safe, making it a convenient material for everyday use.
In addition to laboratory equipment and cookware, high temperature glass is also used in glassblowing. Glassblowers use borosilicate glass to create intricate glass sculptures and ornaments due to its ability to withstand the high temperatures of the glassblowing process.
In summary, high temperature glass is made of a mixture of silica and boron, creating a material that can withstand extreme temperatures and resist chemical corrosion. This makes it an ideal material for laboratory equipment, cookware, and glassblowing.
