Dating glass containers incorporated bottles
Other marks include “ILLINOIS” a brand name apparently used for a line of prescription bottles (similar to their bottles marked “OWENS”); “DURAGLAS“, a trademark used after 1940 and which appears embossed on innumerable bottles of many types; and “LOWEX” another brand name which was used for their borosilicate glass forumula employed especially for power line insulators.Although Owens-Illinois has made containers of many different shades of color over the years, the great majority of glass bottles commonly found (especially older containers that show up often at flea markets, antique malls, yard sales, junk shops, ebay, etc) are made of clear (colorless), green (emerald, forest green or “seven up” green) and amber (“beer bottle brown”) glass.IMPORTANT NOTE: Many liquor bottles and flasks made by Owens-Illinois have a DIFFERENT mold code configuration on the base, as compared to the way the numbers are arranged on most other types of bottles they made.Typically, it is marked with a number called a “Liquor Bottle Permit Number” followed by a dash and a second number which is the date code.This is the very latest instance of use of the “old” O-I mark that I am aware of.Presumably, when this particular mold was pulled out of the storeroom, and used to produce some more bottles (probably for a relatively small order), it wasn’t considered important enough to take the time to re-engrave the trademark.
Other brand names used by O-I on insulators include “Lowex” and “Kimble“.For a page with some of the principal plant code numbers used on bottles, courtesy of Dick Cole (fruitjar.org), click here .(That list is several decades old and does not cover all of the recently started plants).Illustrated among the pics on this page is the base of a bottle made at the Columbus, Ohio facility (plant #18) with a date code of “7” which in this case probably stands for 1937.I don’t know how late the word “OWENS” was embossed as a trademark on the base of those medicine bottles.
