"The earliest glass jars were called wax sealers, because they used sealing wax, which was poured into a channel around the lip that held on a tin lid. This process was complicated and error-prone, but was largely the only one available for a long time, and widely used even into the early 1900s.
By far, though, the most popular form of seal was the screw-on zinc cap, the precursor to today's screw-on lids. The earliest successful application of this was discovered by Mason and patented on November 30, 1858, a date embossed on thousands of jars. Jars with "Patent Nov 30th 1858" were made in many shapes, sizes and colors well into the 1900s. Since they were made in such quantity and used for such long periods, many of them have survived to the present day."
We can attest to that. I am on day three of washing jars. Some more vintage than others. And I have exactly ONE of the famous "Mason" jar as described above. The majority of our stock is Ball or Atlas and range from small "jelly" jars (make awesome juice glasses) to half gallon jars still sporting their zinc lids.
