What is Toughened Glass?

Toughened glass, also known as tempered glass, is a safety glass made by subjecting annealed glass to controlled chemical or thermal treatments. This thermal tempering process puts the glass’s outer surface into compression by subjecting it to rapid cooling, whereas the interior of the glass is put into tension as it remains hot. Because of this compressive strength, when a toughened glass suffers a severe impact, it breaks into small, blunt chunks instead of jagged shards of glass. This makes toughened glass safer than ordinary glass as it is less likely to cause injuries in a rare breakage situation.
