Plastisol lined caps?
Hi - I was poking around looking for some glass jars to use for some bath salts I am making and found some that I'd really like to use for canning as well. I am able to buy plastisol lined caps to use with them. The company says these are safe for canning, but I'm not sure I understand how to process them. First, are these safe? Second, how would I BWB use them?
