Tempered glass is a type of glass that has undergone a special thermal treatment process known as tempering. The tempering process involves heating the glass to a very high temperature and then rapidly cooling it. This leads to the creation of internal stresses within the glass, increasing its strength and resistance to mechanical impacts.

Tempered glass is typically stronger than regular glass. It exhibits high resistance to impacts, thermal fluctuations, and mechanical stresses. If tempered glass shatters, it breaks into small pieces without sharp edges, reducing the risk of injuries.

This property of tempered glass makes it valuable in various applications, including the manufacturing of automotive windshields, glass for doors and windows, glass for furniture, and in architectural uses such as glass railings and shower enclosures. Tempered glass also has good resistance to scratching and chemical exposure, making it durable and suitable for use in various environments.
