Dating antique wine bottles
This website now has a permanent home courtesy of the Society for Historical Archaeology (SHA). This entire website is essentially a "key" - albeit a complex one - to the dating and typing (typology) of historic bottles.In addition, this site also assists the user with these questions: 3.Some of the embossed markings on the bottle base above are a great information source for 20th century bottle identification; some are meaningless.This bottle is an Owens-Illinois Glass Company produced beer bottle made in 1941 by the Oakland, CA. If you are attempting to estimate the approximate manufacturing date - or age - of a particular bottle (or significant sized fragment) the first page to visit would be the Bottle Dating page and its related sub-pages.The lipping tool applied an additional glass band around the opening of the neck and the glass band was then twisted in place, with the support of two other pieces clamped on its outside.
Since there were hundreds of thousands of uniquely different bottles produced in the United States (and Canada**) between the late 18th century and the 1950s (Fike 1987), it is beyond the scope or even possibility of this site (or website or book) to provide specific details about more than just a tiny fraction of a percent of that variety of bottles.

Please note that the main "Bottle Typing/Diagnostic Shapes" page - and many of the subordinate pages - are very large with hundreds of imbedded images; it may take 20 to 30 seconds or more to load even with moderate to high speed internet connections.
Be aware that none of the pages are all inclusive since related information exists on one or many other website pages.
