Tempered glass is a type of safety glass that is designed to be stronger and more durable than regular glass. It is made by heating regular glass to a very high temperature and then rapidly cooling it, which creates a surface compression that makes it stronger than ordinary glass.

Tempered glass is used in a wide range of applications where safety is a concern, such as in car windows, shower doors, patio doors, and skylights. It is also used in many commercial and industrial settings, such as for glass walls and partitions, display cases, and oven doors.
