GLASS FACTORY INFO ~ Dating ~ Antique Bottles ~ Fruit Jars ~ Glass Electrical Insulators ~ Tableware ~ Articles about different kinds of Glassware ~ Manufacturers' Marks used by Glass Companies in the United States: It has come to my attention that some oddly colored Nov 30th 1858-type jars (shades of red and yellow, probably other colors exist) have recently surfaced for sale on auction sites. We can be assured that ALL jars with this mold number are reproductions (modern fakes or ‘fantasy’ jars).

John Landis Mason was awarded patent #22186, issued on November 30, 1858 by the U. Patent & Trademark Office (actually the patent was termed an “Improvement in screw-neck bottles”), for his invention concerning the process of creating a threaded screw-type closure on bottles and jars.

Typically, the base of these jars are marked with “PAT NOV 26 67” (Patented November 26, 1867). In general, any jar with the PAT NOV 26 67 marking on the base can be attributed to the Hero Fruit Jar Company.
Hero had several other glass companies help fill their orders, (such as Marion Fruit Jar & Bottle Company of Marion, IN and Cumberland Glass Manufacturing Company of Bridgeton, NJ) for these jars (which were extremely popular), so it is difficult to be 100% sure exactly where any particular HFJCo jar was made, although assumedly the majority were produced at their factory in Philadelphia.
