Tempered Glass is often used in applications where using standard glass could pose a potential danger. Tempered glass is stronger than standard glass and does not shatter into large shards when broken. This is important, because it can greatly minimize potential danger in the case of a break. Manufactured through a process of extreme heating and rapid cooling, tempered glass is much harder than normal glass.
Tempered or toughened glass is a type of safety glass processed by controlled thermal to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury.
Clear tempered glass is most widely used windows, doors, partitions, shower room, table top, glass wall and so on. It is substrate, it can be processed into printed tempered glass, back painted tempered glass, frosted tempered glass and so on.
