    Why do new Mason jars smell?

    When the lids of your Mason jars are tightly screwed on, the jars tend to develop that musty smell pretty easily because they are closed off to the air. For a compromise, just screw on the lids very lightly so air can still circulate inside the glass jars and so you'll always be able to find a lid when you need one.

    Can you over process canning?

    Over-tightening bands can prevent air from venting out of the jars, resulting in buckled lids or seal failure. After processing, bands may appear to have loosened. You can reuse the jar itself and even the bands, but you can never reuse the Mason jar lid—for canning, that is.
