But in 1858, an inventor and tin smith from New York City, John L. Mason, invented the mason jar. He invented a machine that could cut threads into lids, which made it practical to manufacture a jar with a reusable, screw-on, lid. This was the difference between his design and predecessors, the sealing mechanism: a glass container with a thread molded into its top and a zinc lid with a rubber ring. The rubber created the seal, and the threaded lid maintained it. The jar included his patent: "Mason’s Patent Nov. 30th. 1858." Source: http://www.pickyourown.org/canningjars.htm
