Tempered Glass

Tempered glass is a type of safety glass. The original glass is thermally processed to increase its strength, resulting in a stronger and safer form of glass that is often needed for many applications. Tempering is the process of bringing the glass to temperatures between 600°C and 650°C with special heating systems and then cooling it suddenly with air.

As a result of tempering, compression stress is imparted to the outer surfaces of the glass and an indirect tensile stress (tension) is imparted to the center of the glass. This makes the glass resistant to shrinkage and impact.

While normal glass can shatter into sharp fragments after breakage and cause injury, tempered glass shatters into small, blunt fragments when broken. Therefore, the risk of injury is minimized.
