Exploding glass is a phenomenon by which toughened glass (or tempered) may spontaneously break (or explode) without any apparent reason. The most common causes are: … 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.

Why did my glass table explode?

An uncommon, but unavoidable reason for glass breaking is nickel-sulfide (NiS) inclusions. These tiny particles can get trapped in glass during manufacturing. In toughened glass they sometimes expand slowly and can reach a point where they cause the glass to break.

Can glass be broken by heat?

Hot temperatures can cause the glass to break when the bottle is subject to excessive thermal variations. On the other hand, if a glass container is placed on a very hot source of heat (500°C for example), it can gradually lose its shape and change from a permanent solid form to a plastic state.

What type of glass can withstand high heat?

Based on their heat resistant qualities, there are two types of glass commonly used for a fireplace or wood stove: tempered glass and ceramic glass. Tempered glass is the less expensive alternative, and is best for lower temperature applications. It can withstand constant temperatures of up to 470 degrees F.
