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.

What happens if there are air bubbles when canning?

Trapped air bubbles in the jar produce too much air creating excessive pressure in the jar during processing. The pressure in the jar is greater than the pressure outside the jar during cooling. This imbalance interferes with the sealing process. Air bubbles take up space.

Are the lids supposed to pop when canning?

Most two-piece lids will seal with a "pop" sound while they're cooling, as the lid gets sucked down by the vacuum created by the contents cooling and contracting inside the jar. If it makes a dull sound, the lid is not sealed.
