Tempering puts the outer surfaces into compression and the inner surfaces into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass creates. The granular chunks are less likely to cause injury. As a result of its safety and strength, toughened glass is used in a variety of demanding applications, including vehicle windows, shower doors, glass doors and tables, refrigerator trays, mobile screen protectors, as a component of bulletproof glass, for diving masks, and various types of plates and cookware.

Toughening Glass dictionary - glossary  Harden Glass dictionary glas Nederlands : Process in order to make glass particularly resistant to breakage. The process may be physical (thermal) or chemical. In the physical process, the glass sheet is heated to a temperature just below its softening point and then immediately cooled by cold-air in order to produce a compressively stressed surface layer resulting in a stronger glass item which, upon breakage, shatters into tiny pieces with blunt edges (e.g. used for automotive glass). The chemical process is based on the so-called ion-stuffing technique e.g. glass containing sodium is cooled slowly in a salt bath of molten potassium: the sodium ions will migrate from the glass to the salt, while the potassium ions will move to the surface of the glass where they create a denser and therefore stronger surface layer. Glass sheets which have been chemically tempered are more than five times stronger than those which have not undergone any tempering process.
