Which type of glass is considered oven proof?

Borosilicate glass is considered oven-proof due to its unique thermal properties. It is designed to withstand high temperatures and sudden temperature changes without breaking or cracking. This type of glass is made with silica and boron trioxide, which enhance its thermal resistance. As a result, borosilicate glass is commonly used for bakeware and laboratory equipment, as it can safely go from the oven to the table without the risk of thermal shock.

In comparison, other types of glass, such as lead glass and stained glass, are not suitable for oven use. Lead glass contains lead oxide, which can weaken under extreme heat, while stained glass is typically made for decorative purposes and is not designed to withstand the high temperatures found in an oven. Line glass generally refers to a form of tempered glass used for various applications but does not possess the specific properties that make borosilicate glass oven-safe.
