Tempered glass is a type of safety glass. The original glass is thermally processed to increase its strength, creating a stronger and safer form of glass that is often needed for most applications. Tempering process is bringing the glasses to temperatures between 600 ° C - 650 ° C with special heating systems for this process and cooling them with air suddenly. As a result of the tempering process, compression stress (compression) on the outer surfaces of the glass and an indirect tensile stress (tension) in the middle of the glass is achieved. Thus, the glass becomes resistant to pulling and impacts. While normal glasses may break into sharp particles after breaking and cause injuries, tempered glasses break into small and blunt pieces when broken. Therefore, the risk of injury is minimized.
