Are All Mason Jars Freezer Safe?
No, not all mason jars are freezer safe. Mason jars that are made of tempered glass and have straight sides are generally considered to be safe for freezing. However, those that have a curved design or are not made of tempered glass may break or shatter when exposed to extreme temperatures, making them unsafe for freezing. It is important to check with the manufacturer’s guidelines before putting any mason jar in the freezer.
