Why does glass crack in the freezer?

Glass is a brittle solid. The characteristic "brittle" means that if you apply force, it breaks (cracks) before it bends much.

There are two reasons a glass container may break when it changes temperature.

1. If the glass object contains a solid that changes size with temperature so that it becomes larger in size in size than the glass container, it exerts a force on the glass and if the force is large enough, the glass will break. Here is a discussion of that.

In reality, no the glass will not crack unless you have stored something inside that will expand (water based) when it freezes. It is not the temperature that cracks the glass, more the expansion of the contents will exert great pressure on the walls of the container.

A non-messy example can be made simply but filling a small plastic (not brittle) bottle to the brim with clean water, adding a lid and then freezing it. You will find the ice will have made the bottom of the container bow out (or possibly break) as a result of the increased volume ice has over water.

If you take a jam jar, fill it with water to the brim and place a lid on then freeze it, the jar will crack. If however you fill it with a substance that will either not freeze or is not water based (so doesn't have the expansion issue that water does when it turns to ice) then the jar will be fine.

2. Glass, like most materials, changes size when heated or cooled. If a glass object is heated or cooled so the temperature is different in different parts of the object, then the different parts of then a stress is created because the object is being stretched in a nonuniform fashion. Stress is a force. Strain is the distortion due to the force. If the object is brittle, then nonuniform strain will cause it to crack.

In practical terms that means that brittle objects can will crack unless heated slowly so that temperature is nearly uniform and strain is small.

That is also why the kind of glass used in cooking is different than the kind of glass used for holding liquids. Some forms of glass are more brittle than others.

Can glass be put in freezer?

Yes. For instance, you can chill a glass that you are going to use for a cold beverage. Warning: A closed glass container can explode and spread shattered glass all over the inside of your freezer if it is too full. Liquids expand when they freeze, and if there isn't enough room for them to expand inside the container, they will burst out of it. This can happen with other containers, too, but you won't see the wreckage that you get when it happens with glass. It's the kind of mistake you don't make more than once. Yes, but it is likely to crack if you fill it up with liquid and then seal it. NEVER stack two or more glasses in the freezer. Stacked glasses act just like a closed glass container when placed in the freezer and will break, even when there is nothing in them.

Why do glasses break in the fridge and freezer?

Because the glass gets cold and to form the figure it was in it had to expand with heat therefore putting a glass in an extremely cold enviornment like the freezer the glass particles get compact (really tight) and shatters.

Does heat cause stress fractures?

This depends on the type of window/glass as some glass is thermally treated. However, stress in the glass from contraction/expansion can make a noticeable crack. Heat alone will not crack glass but it will, over time, melt it.


Would glass or plastic shelving be better in a freezer and can you explain your choice?

Plastic shelving would be better in a freezer than glass because the extreme cold would make the glass more brittle and thus more likely to break.
