Why the glass lid exploding on its own?
Jan 07, 2019

There are many reasons for the cracking of tempered glass, summarized as the following:

1. Influence of glass quality defects: the part of glass containing stones and impurities is the weak point of tempered glass and also the stress concentration. Especially if the stone is in the tensile stress zone of the tempered glass, it is an important factor leading to the rupture.

2, Due to the heating process or improper operation resulting in scratches, blasting, deep burn-edge defects,it is easy to cause stress concentration or lead to self-explosion of tempered glass.
