Wide Mouth Mason Jars
Classic glass canning jars for preserving, freezing, and storing food with two-piece vacuum lids
About
Classic tempered glass canning jars with two-piece vacuum seal lids. Suitable for canning, freezing, and dry storage. Wide mouth design allows easy filling and cleaning.
How It Works
Ball mason jars use a two-piece lid system. The flat lid has a sealing compound that creates a vacuum seal when processed, while the band holds the lid in place during processing. After processing, the vacuum holds the lid sealed even without the band.
For canning, fill jars with prepared food, wipe rims clean, place lids, and screw on bands fingertip-tight. Process in a water bath or pressure canner depending on the food. For freezing, leave adequate headspace (about 1 inch for quarts) and use straight-sided jars to prevent cracking. Mason jars are also excellent for dry storage of grains, beans, and dried herbs. The wide mouth makes filling and cleaning easy.
