What type of glass can withstand high heat?

What glass can withstand high heat? 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).

Why are my mason jars breaking?
