canning

My grandma had an old one with just a weight and no guage... She said she could tell the right temp by the sound it made.

Like when you try canning with a turkey-fryer burner.

I KNOW that got your attention.

Most of the single ones were actually 3 in ones. I have seen many that after a few batches do not just fall apart and people never knew. a true one piece solid will start its dance at 15 lbs. And yes they have a particular sound. The 3 piece with all intact are 15 lbs. This was to insure that you got enough pressure no matter what since 15 psi is good to 10000'.

Here are my two cheat sheets I hand out in my canning class.
