    An update on this thread ... I did a batch of salsa the other day and tried one of the old jars with a new lid and the zinc band. The jar did not seal.
    I'm very disappointed as I have so many of these old jars and I would really like to use them.
    These old jars and so nice, you would think someone would have invented a modern lid to fit!

    I wonder if the pressure on the new lid was sufficient as they are so much thinner than the rubber rings. I would be tempted to try again but put an old rubber ring on top of the new metal one so that there is more pressure on top the lid when the top is screwed on.

    You might also try dipping the rings in melted food grade paraffin and let them solidify before using them. The paraffin will seal any possible holes that would cause them to go bad . If using them for salsa be sure to add additional vinegar when you make it. That will raise the acid content and prevent some of the nasty bacteria.
    How long are you processing the jars ?

    I processed for 35 minutes, following the recipe. The old jar with new lid is the only jar that did not seal.
