Example of an all In one Canning Jars and Lids System
The Evolution of the Two Part Canning Jars and Lids System
Old canning systems used to have both canning jars and spring loaded lid systems – all in one.
The newer two part systems consist of a two part jar and lid system. When the lid or seal wear out, they can be replaced, and the jar is reusable. The only time you should not use a canning jar anymore is when it is chipped as the seal can be disrupted.
You can now purchase glass canning jars in flats with ten to twelve jars – lids and rings are included. Check out Wall Mart or Target for flats of canning jars and lids.
I have a large 2 part lid. It measure 4″ in diameter. Can you tell me anything about it?
