How hot can tempered glass get before it breaks?
320 degrees CelsiusHow hot can tempered glass get before it breaks? The thermal stability of tempered glass is 1.5-2 times better than annealed (regular) glass. This means while annealed glass would crack at 100 degrees Celsius, tempered glass can withstand temperatures of up to 320 degrees Celsius before cracking.
