30th 1858” date became generic on fruit jars made by numerous glass companies. 30, 1858 patent, probably with the embossed date, were being made by some unknown glass house as early as June 25, 1859, when an ad for “Mason’s Patent Sheet Metal Screw Top Preserve Jars” appeared in the Pittsburgh Dispatch.

There are hundreds of different “1858” jars, made in sizes from half-pint (extremely rare) to four-gallon (made for exhibition purposes), and their colors range across the spectrum, including clear, sun-colored-amethyst, aqua, green, amber and blue.

These colors also come in many shades, such as green-aqua and blue-aqua, light green and emerald green, light honey amber and dark amber, cobalt blue and teal blue, and all the shades in between.

It sounds quite feasible for the time, but unfortunately, there are no known examples made precisely to this patent.

One of the earliest jars recognized as a fruit jar is the wax sealer.

These jars, which were made in different forms, have a grooved channel around the mouth opening.

A tin or pottery lid (in the case of some pottery jars) was placed on the jar with the side walls of the lid descending into the groove.

Fruit jar development made it possible for the commercial canners to develop ways to provide us with canned fruits and vegetables that would otherwise be unavailable during much of the year.

Today’s collectible fruit jars were the indirect result of Napoleon’s desire to rule all of Europe – and possibly the world.

Commercially-made fruit jars date from the 1850s, with the first known patent for an “Improvement In Bottle Fastenings” that was granted to James Spratt, of Cincinnati, Ohio, on Sept. Spratt’s patent called for a glass stopper to be sealed in the jar mouth with “cement,” or sealing wax.

The stopper had a hole in the center through which the steam could escape during the boiling process; this hole was to be stopped with a drop of cement when the processing was complete.

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.

This patent date was to be embossed on millions of fruit jars, both hand-blown and machine-made, over the next 50 years or so.
