Why Do Mason Jars Break in the Freezer
Mason jars are a popular choice for canning and preserving food, but they can also be used for storage. Many people choose to store mason jars in the freezer, but there is a risk that the jars will break.
The reason mason jars break in the freezer is due to the expansion of water inside the jar.
When water freezes, it expands and this can cause the glass jar to crack or break. It is important to remember that even if a mason jar does not contain any water, it can still break if it is exposed to extreme cold temperatures.
There are some steps you can take to help prevent your mason jars from breaking in the freezer.
First, make sure that you leave some headspace at the top of each jar before freezing. This will allow for expansion of the water and will help reduce stress on the glass. Second, do not stack jars on top of each other when freezing – this can add pressure and increase the chance of breakage.
Finally, try not to expose your frozen jars to sudden temperature changes – such as taking them out of the freezer and immediately placing them into boiling water.
Conclusion
Are glass mason jars freezer safe? Yes, they are! You can store them in the freezer for up to three months.
Just make sure to leave some headspace at the top of the jar so that the food doesn’t expand and break the jar.
