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.
Can tempered glass break by itself?
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 is tempered glass so brittle?
During the tempering process, plate glass is heated up to its softening point, then rapidly cooled. It is this expansion that can create a weak spot in the toughened glass and which can, sometimes at a much later date, cause spontaneous glass breakage.
Can you break tempered glass with a hammer?
When you strike the flat surface of tempered glass with a hammer, the force of the blow is spread out across a broader area so that it doesn’t shatter. If the hammer blow is at an angle or if the hammer head is very small or pointed, rather than flat, you can break tempered glass.

What temp does glass crack?
When heated, thin glass begins to crack and typically breaks at 302–392 degrees Fahrenheit. Glass bottles and jars are usually not affected by ambient, refrigeration or warm temperatures. However, high heat (>300°F) and excessive thermal variations can cause glass to shatter or break.
When should I replace my tempered glass?
Always remember that if there’s any pits or cracks in your tempered glass screen protector, you should replace it, even if they’re minor. Glass has a habit of turning minor cracks and pits into major defects.

Why does tempered glass shatter spontaneously?
Any flaw in the edge or glass surface can cause spontaneous breakage. Small cracks in glass grow over time. As the glass expands in the heat and contracts in the cold this crack will grow. Eventually, this change in temperature can cause the tempered glass to shatter.
Does tempered glass crack easily?
Although tempered glasses don’t easily break. The impact can break it. For example, a tempered screen protector can handle low drops. But dropping it from a higher altitude and with more force tends to create cracks and scratches.

Can tempered glass break in cold weather?
While tempered glass is stronger than regular glass, it is not indestructible. It can break like any other glass furniture when exposed to blunt force or extreme fluctuations in temperature. Tempered glass should be able to withstand snowfall and cold temperatures, so long as they aren’t extreme.
