Toughened glass is also known as tempered glass which is a kind of safety glass manufactured by under control thermal or chemical treatment to boost its power as compared to the glass commonly available in the market. When tempering process is applied it adjusts the exterior surfaces to compression as well as the interior surfaces to tension. This stress presses to crush into tiny grainy chunks rather than chipping to jagged shards usually plate glass generates. Hence, the chances for granular chunks to cause damage are rare.
Due to its power and safety, toughened glass is exploited in a wide range of the prevailing applications comprising shower doors, passenger vehicles, tables, chairs, architecture glass, mobile screen protectors, glass pool fencing, acting as an element of bullet proof glass for the purpose of diving masks, as well as miscellaneous plates of various types & cooking appliances. Toughened glass is practically more powerful than commonly used glass due to the special process it has to undergo through as stated above. The higher contraction of the interior layer during the process of manufacturing generates compressive tensions to the glass surface stabilized by tensile tensions in the glass body.
As for glass is regarded to be toughened, this compressive tension onto the glass surface usually approximates 69 megapascals 10000 psi minimally. As far as it to be comprehended the safety glass, the compressive stress of the surface of the glass goes beyond 100 megapascals 15000 psi. The higher the surface tension is, the less the glass particles will take place at the time of the breakage.
It so happens that this compressive tension or stress provides the toughened glass with the increased powerful features. Of course, because the surface defects of any kind are inclined to be pushed down nearly by the restricted compressive powers, at the same time; the core layer is comparatively independent of the faults that are liable to bring about a cracking to go.
