What temperature water will crack glass?
Glass is a poor thermal conductor and rapid changes in temperature (roughly 60°F and greater) may create stress fractures in the glass that may eventually crack. When heated, thin glass begins to crack and typically breaks at 302–392°F.

Thermal fracturing in glass occurs when a sufficient temperature differential is created within glass. As a warmed area expands or a cooled area contracts, stress forces develop, potentially leading to fracture.
