The glass tempered by Almaty a glass Hardening

Training flew down

The tempered glass (STALINIT) is the glass which passed the special heat treatment technologically similar to process of a hardening became. As a result of process of a hardening durability of glass increases several times, and in case of destruction red-hot glass is scattered in a small crumb. Feature of such tempered glass is the impossibility of its subsequent processing after passing of process of a hardening therefore such operations as open glasses, drilling of technological openings, polishing of an edge are carried out before sending glass to the furnace. From the point of view of technological process the tempered glass (red-hot glass) represents the sheet glass subjected to thermal training processing as a result of which in the mass of glass there is distributed internal tension which increases the mechanical durability of glass and provide its special (safe) nature of destruction. In other words, process of a hardening of glass is a process of temperature processing thanks to which initial glass becomes stronger. Even if casual mechanical influence took place, the tempered glass fights in a small crumb that practically nullifies probability of getting injured and cuts. The tempered glass at destruction does not form large splinters, and splinters of red-hot glass have no the pointed ends.
