Quick answer: What Does It Mean If A Glass Breaks By Itself?

Does glass break with heat?

The glass breaks on heating due to thermal shock.

Whenever there is difference in temperature between two surfaces of the glass, the thermal expansion of one side with respect to other side induces stress in the material.

When this stress reaches above the yield strength of the material the cracks start to develop..

Why would a glass shatter for no reason?

Spontaneous breakage of tempered glass is most commonly caused by chipped or nicked edges during installation, stress caused by binding in the frame, internal defects such as nickel sulfide inclusions, thermal stresses in the glass, and inadequate thickness to resist high wind loads.
