What is the highest temperature glass can withstand?
Ceramic glass is best for higher temperature applications. It can withstand constant temperatures up to either 1256 degrees F (PyroCeram®, 1/8″ or 3mm thick) or 1470 degrees F (NeoCeram®, 3/16″ or 5mm thick). It is actually not glass, but a polycrystalline, transparent ceramic material.

Why does glass crack when hot water is poured in?
