For urban families, Mason Jars allowed excess fruits and vegetables to be preserved for use later.
These jars carry the familiar embossing "Mason's Patent Nov. This date refers to the original patent date, not the actual date of manufacture.
Bottles, jars, jugs and containers of all types, antique fruit jars, glass insulators, fishing net floats, EAPG (Early American Pattern Glass), Depression Glass, antique children’s mugs, and other items are some of the forms of glass I enjoy learning more about.
I’m interested in the general history of the glass manufacturing industry in the United States, especially within the sphere of container glass, electrical insulators and tableware (both pressed and blown).
Five of the webpages within this site list glass manufacturers’ identification marks (alphabetically listed) found on container glass (bottles, jars, flasks, jugs, etc) and in some cases on other types of glassware.
A few examples of marks would be “I inside a diamond”, “OWENS”, “B in a circle” , “K in a hexagon” and “N in a square”.
It was extremely hot (especially in the warmer months), noisy, and dangerous for a number or reasons.
Injuries, especially burns and cuts, were commonplace.
Lightning jars represent an important advancement in the history of home canning and are still a part of American culture.
To read any of the “glass manufacturer profiles” I’ve posted (so far), and other articles pertaining to glass, please look along the right-hand side of any page for the list of , and click on any link in that list.
I hope to add more information as time and energy permits! factories, a few Canadian and Mexican factories are listed also. If you have additional information, please contact me (at the email address listed at the very bottom of any page on this site) as I’m continually looking for the most available on these companies.
Fire was always a potential occurrence, and many early factories were destroyed by fire, sometimes leading to the complete closing down of a plant and/or failure of a company.
Antique and vintage glassware of all types and styles that are collected, studied and appreciated today are the tangible artifacts and testaments to the remarkable creativity, sheer hard work, energy, perseverance, and innovation of those men (and some women) who worked in those earlier factories.
One page in particular within this site is a list of glass factories that manufactured, or are believed to have produced, glass electrical insulators for telegraph, telephone and/or power lines. Sources of some of the information is included after each entry if I have it available.
