When excellent the best way, her glass containers shouldn’t break once frozen. Why climate does this happen to so countless people? Well, there space a few things that can lead come this.

The first, and most obvious, is the components of the glass container. Unlike many things, water actually broadens as the freezes. With that gift said, if her container contains liquid (or foodstuffs high in water content), it might break because of the push put on that by the liquid within of it.

Also, not all glass is recommended for freezing. When you could not operation into any kind of issues v non-tempered glass, it’s lot safer to use tempered glass, when possible.

Tempered glass is much stronger and also doesn’t contain tiny pockets that air, choose non-tempered glass, which deserve to expand and also contract v temperature fluctuations.

Another factor for glass break in the freezer is as soon as a container is subjected to a fast temperature change. For example, if you take it a warm casserole dish and also place it into the freezer, you’ll operation the threat of break the casserole dish because of the far-reaching change in temperature during a short period of time.

How to save Glass from break in the Freezer

In the section above, I extended a couple of reasons why glass containers have tendency to break as soon as frozen. Now, let’s take it these observations and also turn them right into some easy-to-follow rule to use any time you freeze glass.

1 – usage Tempered or Freezer-Safe Glass


Not all glass is produced equal. If you setup on freezing foodstuffs or liquids in glass jars or containers, always opt because that tempered glass or glass labeled together freezer safe, prefer this set, which is labeled together safe because that the freezer, microwave, oven, and also dishwasher.

As mentioned earlier, non-tempered glass has tiny pockets that air, which deserve to expand and also contract as the temperature that the glass changes.

Tempered glass, top top the other hand, is lot stronger and can handle temperature changes just good (assuming the remaining pointers in this post are preserved in mind). Canning jars are commonly safe because that freezing, so one of two people look because that these, or look because that something labeled as freezer safe.

2 – leave Headspace

As I discussed above, as soon as water freezes, it expands. This is just one of the most usual reasons because that glass division or cracks in the freezer. To protect versus this, merely leave some room for development in her food container. This is regularly referred to together headspace.

By leaving a bit of space at the peak of your container, the contents will simply increase upward, pour it until it is full the empty space. Simply be mindful of the following tip as well…

When put glass containers in the freezer, don’t placed them near any kind of freezing components, and don’t placed them straight on height of various other frozen items. This will topic the glass to also drastic of a readjust in temperature, which might lead come a glass break.

When thawing your frozen items, you’ll desire to reverse the process by very first loosening the lid, then putting the container in the refrigerator to thaw, then finally allowing the container to warm up to room temperature.

Instead, leave part “breathing room” in between them come prevent any type of pressure transforms from one container to have an effect on the containers sitting directly next come it.
