Do Mason Jars Explode In The Freezer?
Yes, Mason jars can explode in the freezer if they are not properly designed for freezing or if they have been overfilled with liquid. When liquids freeze, they expand and can cause the glass to break if there is not enough room for expansion. It is recommended to use freezer-safe glass containers or leave enough headspace (about 1 inch) when freezing in Mason jars to prevent any potential explosions.
