Source: LandGlass  Attention: 843  Published: 2014-10-20

Spontaneous explosion tends to occur to tempered glass and the following reasons account for it:  

1. There are nickel sulfide particles in the glass sheets;

Solution: check the quality of the glass sheet to see if there are stone like impurities, nickel sulfide particles and bubbles inside the glass and to see if there are scratches, nick and deep micro cracks left on the glass surface, etc.

2. The stress of the tempered glass is too high;

Solution: reduce the heating temperature or the heating time, or lower the air pressure in the tempering section.
