Heat-resistant glass is used by people all over the world for a wide range of tasks, including cooking, laboratory work, and even rocket construction. Here, Cameo Glass’ latest blog examines the core properties of heat-resistant glass, before explaining its main benefits and providing a sneak peak at the production process.
The answer to this is quite self-explanatory; heat-resistant glass can withstand high levels of heat without cracking or shattering.
Many of you may already be familiar with this type of glass through one room in particular – your kitchen. You may have heat-resistant glass in your cupboards in the form of Pyrex dishes, which are suitable for oven cooking, and the glass in your oven door or on the surface of your hobs. You can buy this heat-resistant glass in differing strengths, with the strongest variant perfectly equipped to prevent the spread of fires.
Heat-resistant glass’ strength against heat depends on its chemical composition. Borosilicate glass is the least heat resistant; the difference between this glass and normal glass is the addition of boron oxide, which helps bind together the components that provide its heat-resistant properties. This glass is commonly used for cookware and even in laboratories.
The second most heat-resistant glass is Aluminosilicate, which contains aluminium oxide and can withstand temperatures of 800° celsius as a result. It is also scratch resistant, making the glass a common feature for touch displays on devices such as smartphones. The most heat resistant type of glass is high silica glass, which can withstand temperatures of around 1000° celsius and is mainly only used in industrial settings – taking this a step further still, the next next level above high-silica glass is fused quartz, which is used for aerospace applications.
