Traditional Jars

To use a traditional glass mason jar for freezing, you need to leave adequate space at the top of the jar. Traditional jars are apt to burst in the freezer because of water expansion and improper cool-down times before canning. As jars cool, the contents in the jar contract, pulling the lid firmly to the jar.

Wide-Mouth Jars

Freezer-safe wide-mouth jars have openings of 3 inches, making it easier to put food into the jar and take it out. These tempered glass mason jars are shatter-resistant and are ideal for sauces, fruits, pickles and juices. Wide-mouth mason jars come in 16-, 32- and 1814gr. sizes.

Regular-Mouth Jars

Freezer-safe regular-mouth jars come in crystal-cut or regular tempered glass. Use these jars to can and freeze smaller batches of sauces, jams and jellies. Regular-mouth jars come in 4-, 8-, 12-, 16- and 907gr. sizes.
