Hi David, My grandmother sometimes used jars that were not made for home canning either. Judy and I do not use them however as they sometimes break in the canner. Never use the jar lids that come with these jars. We only use the rubber sealed lids once. The rings can be reused as long as they do not rust or become deformed. Allen Bastrop Co., SE Central Tx.
