Can the company / maker be identified by the markings on it? All of these questions might come to mind to the collector or layman, flea market shopper, historian, archaeologist, or casual hobbyist………..
and my site attempts to answer, in at least some cases if possible, a couple of these questions: Where, and approximately when, perhaps, was this piece of glass made?
For a brief, basic discussion on glass (especially concerning the most common type of glass used for containers and tableware), check out my webpage here: What is Glass? Where was the physical location of the sand supply that eventually was turned into the glass piece that you hold in your hand?
Every glass object, even the most lowly, commonplace glass bottle, has a story behind it, although all of the precise details may never be known. What was the name of the company or factory where it was produced? Is it American-made, or a piece that was produced outside the United States?

The German mathematician Carl Friedrich Gauss (1777–1855), in connection with practical problems of surveying and geodesy, initiated the field of differential geometry.It is one of the oldest branches of mathematics, having arisen in response to such practical problems as those found in surveying, and its name is derived from Greek words meaning “Earth measurement.” Eventually it was realized that geometry need not be limited to the study of flat surfaces (plane geometry) and rigid three-dimensional objects (solid geometry) but that even the most abstract thoughts and images might be represented and developed in geometric terms.By the late 19th century the hegemony of Euclidean geometry had been challenged by non-Euclidean geometry and projective geometry.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.This is an ongoing project, started in 2004, and I’d appreciate any additions, corrections, or suggestions you may have!
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.
