Can someone help me with an stimated value on this lip. This is the history that I found so far:
In 1859, Mason sold five of his early patents, including the mason jar, to Lewis R. Boyd and Boyd’s company - The Sheet Metal Screw Company. Boyd is most famous for patenting a white "milk-glass" insert for zinc screw lids to theoretically lessen the chances that food would come in contact with metal. In 1871, for a brief period of time, Mason became a partner with Boyd in the Consolidated Fruit Jar Company. Consolidated hired other glass makers to blow their jars, including the Clyde Glass Works, Clyde, New York, the Whitney Glass Works of Glassboro, New Jersey, and the A. & D. H. Chambers Company of Pittsburgh, Pennsylvania. Even after Mason’s patents expired, the manufacture of these jars continued for well over half a century. The companies that produced the Mason jar between 1859 and 1910 are too numerous to mention." From FOHBC Primer.
With the domination of the canning jar industry by the mason jar, and the Lightning jar, by the 1880's innovation was on the decline in the canning jar industry. While patents did continue to be granted, fewer and fewer resulted in jars being produced, but rather the patents covered improvements in sealing the jars. This is seen in the modern jars of today, with the two piece metal closure, that seals on the top of the lip of the jar. While this idea was patented in various forms in the late 19 th and early 20 th century, it was not until after WWII that the technology behind it was perfected, and it gained wide usage in households.
