For the most part, I have not attempted to list fine distinctions for marks that are found both with and without periods. See my webpage here with more info on numbers seen on bottles.

Another source of confusion was the common practice of engraving the “G” (especially in the 1880-1920 period) to appear very close in similarity to a “C”, the only difference between the two being a small “tail” pointing in a downward or “southeasterly” direction on the lower right-hand side of the letter G. I will occasionally be adding more data to these pages as I uncover more accurate information.

This is very frequently the case, especially with soda, mineral water, beer and other bottles of the 1880-1930 period, in which the initial(s) of the “end user” (such as the bottler, brewery, drug manufacturer, or other firm for which the bottle was made) appear embossed on the base. initials of early glass companies) may vary slightly in appearance and punctuation from one bottle to another. These marks usually served as some type of mold identification, indicating a particular mold used by a glass factory.

If it’s a question that is already answered somewhere on this site, then a *keyword search* will have to suffice (look along the top right-hand area of any page for the search box), and I may not reply with an individual answer.he has a extensive list with alot of great material on obscure glass and pottery companies here: Manuf Beer ******************************************************************************** Usually embossed on the base, marks may also appear on the lower heel area on certain types of bottles, especially sodas.On earlier flasks, fruit jars, and soda bottles, and especially examples produced in the mid-nineteenth century period (1840s-1860s), the full factory name or initials may be embossed across the front.This list primarily includes marks that represent the actual glass company that made the container.Many marks are encountered that indicate the company whose product was contained within it, or are trademarks (“brand names”) that give no indication of who actually made the glass, and those are (with quite a few exceptions) , not included in my list.One can find quite a bit of information on my web site and across the Internet about dating bottles based on whether the mold seam goes up and over the lip or if the bottle has a 'pontil' on the base.
