Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments 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. Toughened glass is a kind of safety glass.
Toughened glass can be made on customer's request, clear toughened glass, ultra clear toughened glass, colored tinted toughened glass, printed toughened glass, back painted toughened glass, frosted toughened glass, toughened Laminated Glass, toughened Insulated Glass, toughened Vacuum Insulated Glass and so on.
