Tempered Glass
The tempering process is the process of heating the glass to temperatures between 600°C and 650°C with special heating systems and then cooling it suddenly with air. The surface hardens as the temperature decreases. As the outer parts and then the inner parts cool, pressure is created on the glass surfaces and tensile stresses are created on the inner part of the glass.
While tempered glass can withstand a thermal shock of 300°C, untempered glass can break when exposed to a thermal shock of approximately 40°C.
