The Mason’s Improved jars were also made by many glass companies, both for Mason and by just about everyone when Mason’s rights to this patent were voided by the U. One of the next major developments in fruit jar closures was the Lightning-style glass lid and wire clamp arrangement patented by Henry W. This closure was actually adapted from a bottle patent issued to Charles de Quillfeldt in 1875.Putnam acquired rights to de Quillfeldt’s patent and adapted it for use on fruit jars.Unfortunately, most of the 1858s found by new collectors will be clear or aqua and of nominal value due to the number still being found.The teal blue half-gallon jar has a market value today somewhere above ,000; the amber 1858 quart, about 5-0; and the midget keystone 1858 pint, about . 30th 1858” quarts, ground or smooth lip, are valued at only about to a collector, and they are often difficult to sell at that price. Mason again hit the mark with his patent for a glass top-seal lid and screw band, granted on May 10 of that year.
Today’s collectible fruit jars were the indirect result of Napoleon’s desire to rule all of Europe – and possibly the world.
Most of these jars are affordable for new collectors, but many can still provide a challenge to find. These closure styles accounted for the vast majority of fruit jars used up until about 1930, but there were plenty of other odd-ball closures patented and produced that bring joy to today’s jar collectors.
Lightning closure clear fruit jars were made for home canning by both the Atlas Glass Co. Everybody, it seems, knew how to build a better mouse trap—or fruit jar—and many of them put their ideas into tangible form.
This “Mason’s Improved” closure, as it was called, was intended to eliminate the taste of zinc picked up by the canned food from the zinc shoulder-seal caps.
With this new patent, the food could only come in contact with the glass lid or the rubber gasket beneath it. Strangely, their life span was less than either the zinc-cap closure jars or the Lightning-style jars, apparently being dropped by the major glass companies around 1920.
