Why does glass break when heated?

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 explode?

The most common causes are: Minor damage during installation such as nicked or chipped edges later developing into larger breaks normally radiating from point of defect. Binding of the glass in the frame, causing stresses to develop as the glass expands and contracts due to thermal changes or deflects due to wind.
