Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to shatter into small granular chunks instead of splintering into jagged shards as ordinary annealed glass does. The granular chunks are less likely to cause injury.
Ceramic Glass
Ceramic glass is a powerful formula! It is a combination of tempered glass (which is already 7 times stronger than regular glass) and ceramic. This material is also called Pyroceram. It makes for a shatter resistant product that can withstand a thermal shock rating of 1380°F and intense heat up to 1400°F
