Both Aussie Mason and Ball Mason jars are water-bath and pressure canning safe.
The wide mouth jars of each brand with straight sides are freezer safe (with the appropriate headspace allowance for liquid expansion).
Both brands come with two-piece preserving lids, a single-Use Flat lid that has its own inbuilt seal, and a reusable screw-on band to hold the lid in place during the preserving process.
They are made from American FDA Approved Tempered glass and are BPA-free.
Each comes in a variety of sizes and their lids are interchangeable between brands.
