Ball Mason Canning Jars

Yes, these Ball Mason jars are specifically designed for home canning and are tempered to withstand the heat required for water bath processing.

While glass can be used in the freezer, it is risky. If you choose to freeze them, leave at least an inch of headspace at the top to allow for expansion, and avoid sudden temperature changes to prevent the glass from cracking.

The glass jars are dishwasher safe, but it is recommended to hand wash the metal lids and bands. The dishwasher can cause the metal to rust or the sealing compound to degrade over time.

Regular mouth jars have a smaller opening, which is ideal for liquids, sauces, and smaller fruits or vegetables. Wide mouth jars have a larger opening, making them easier to fill with bulky items like whole pickles or large produce.

This pack includes the standard lids and bands required for initial use. If you plan on reusing the jars for canning, you will need to purchase new flat sealing lids separately, as the rubber compound is designed for a single use to ensure a proper vacuum seal.
