(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.
