Mason Jar

This item is related to the small crock that was featured last time. In 1810, Nicholas Appert invented a way to seal food inside glass jars using a vacuum seal. John Landis Mason patented the first screw top jar in 1858. Jars like these were fitted with a zinc cap and a rubber gasket that went around the neck to seal the jar. Canning with jars like this became popular in the Big South Fork area around the 1920s, making the small crocks and beeswax technique obsolete. Jars like these were good for holding any manner of contents. Notice that this jar has the November 30th, 1858 patent date for the Mason screw closure.
