Tempered Monolithic Glass
The "Securit" tempering process was discovered in Saint-Gobain's laboratories in 1929, in the course of research undertaken at the request of the automobile industry. The process, which consists of strengthening the glass by very fast blast cooling (from 600 to 300° C in a few seconds), is used to make automobile, building, and specialty flat glass. Tempered glass is also a safety glass. A violent impact shatters tempered glass into many tiny non-cutting fragments.
