In the United States, however, a variety of canning jars began appearing in the late 1840s.

While stoneware crocks were used for many things, they did not enable the homemaker to seal the container securely and so the contents were always at risk.

John Mason was a tinsmith in New York and perfected a machine that would cut threads into the lids, creating a jar with a reusable, screw-on lid.

The information has been obtained from various sources or based on my collecting experience and is true to the best of my knowledge.These humble glass pieces were designed for putting up fruits and vegetables in the days before refrigeration.Hazel Glass Company, Washington, PA (began 1887) and Atlas Glass Company, also of Washington, PA (began 1896) merged to form the Hazel-Atlas Glass Company, Wheeling, WV, in 1902. (In my own opinion, it is likely, or at least very possible, that the “H over A” mark continued to appear on some containers produced after 1964, since a very large number of molds were then in use, and it would have been a considerable endeavor just to make minor re-tooling changes on all of those molds to erase or replace the makers mark.) Tremendous numbers of white milkglass liners (the miniature round glass plates or “saucers” that fit inside zinc screw-threaded lids made for Mason-style fruit jars) were produced, as well as canning jars (fruit jars) including the jars for general household use; “packer ware” (generic containers for a multitude of common food products such as mayonnaise, spaghetti sauce, mustard, jams and jellies, coffee, peanut butter, applesauce, etc, as well as non-food items like cosmetics, salves, medicines, chemical liquids), as well as a wide variety of other containers for products of every description.These jars freed farm families from having to rely on pickle barrels, root cellars, and smoke houses to get through the winter.For urban families, Mason Jars allowed excess fruits and vegetables to be preserved for use later.
