The increase in the number of people cooking and trying recipes during the pandemic has led to a surge in canning – because experienced canners are doing it more and novices want to give it a try. And that surge has led to a shortage in Mason jars and lids.

These are called mold numbers. They identify the position that the mold in which the jar was made held on the glassmaking machine. Most machines would have from eight to ten molds, all making the same type of jar.
