Some Unknown / Unidentified Marks on Glass Bottles

A Selection of Unknown / Unidentified Marks seen                   on bottles)

These marks are shown elsewhere on this site, in the alphabetical mark listings, but I wanted to create a webpage here with some of the  unknown (so far)  marks gathered  in one place.

If you have information that could help with identification on any of these marks seen on glass, please write and let us know!  My email is listed on the “Contact Information” page.

THANK YOU SO MUCH to all who have submitted photos of bottle bases over the years!
