Considerable stress can build around chips, cracks, or other imperfections in the edges of a tempered glass window. Over time, environmental stressors like temperature, wind, and road vibrations can put those glass imperfections under even more stress, which triggers spontaneous breakage.
Can a car window shatter by itself?
Sometimes a car window can shatter almost spontaneously, such as when the vehicle door is closed particularly hard. While these incidents can seem inexplicable, a type of unaddressed damage is to blame.
Can heat cause glass to shatter?
However, high heat (>300°F) and excessive thermal variations can cause glass to shatter or break. 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.
Can I keep glass in a hot car?
Glass bottles are also very sensitive to temperature changes. If left in a hot car, the wine inside the glass bottle will expand and the bottle might burst or the wine might seep around the cork.

What glass can withstand heat?
Tempered glass can withstand temperatures up to 470 degrees Fahrenheit. Because it is heat resistant, tempered glass is ideal for kitchen appliances and for use in areas that may regularly be in contact with heat.
How do you heat glass without cracking it?
If you want to prevent the glass from cracking, you should aim to reduce the temperature difference between the inner and outer layers. Here are some ways to do that: Pour the hot water (very) slowly into the glass. Put a metal spoon in the glass to conduct away some of the heat.
How do you cool down glass quickly?
Water and ice gets a glass down to its coldest temperature—just above the freezing point of water—in about 6 minutes.
Does glass break from hot to cold?
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.
