If the stress of this expansion overcomes the structural integrity of the glass, a crack forms, often originating at the edge. Identifying a Thermal Stress Crack The crack happens when the between the center
A is a type of window fracture caused by significant temperature differences across a single pane of glass. When one part of the glass expands due to heat while an adjacent part remains cool and contracted, the resulting internal tension can exceed the glass's strength, causing it to snap.
