Can glass jars be used in freezer?

Answer 1

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.

Answer 2

Although some of the more modern types of glass will handle going from ice-cold to very hot just fine, it's usually a very good idea to let the glass defrost before heating it.

If you need it ready in a hurry, set the glass and its contents in a shallow pan full of warm, NOT hot, water and let it rest there until the water cools. Change out the water, continue this until the glass is no longer frozen.

If you're still unsure whether or not it is safe, don't risk it. Nothing ruins perfectly good food like shards of glass.

Answer 4

Jars made for canning can be used in the freezer. You need to leave extra room inside for the food to expand as it freezes to avoid breaking the jars.
