This identified the bottle as their “No 766” mold in bottle catalogs and/or communications with buyers.

Owens Bottle Company produced tremendous numbers of bottles, jars and other containers with the “O inside a square” or “Squared O” mark which is also frequently seen on bottles from the 1920s.

The name “LYRIC” was used by Illinois also, and this is a brand name they assigned to a line of pharmaceutical (prescription) bottles, and is often seen on the base of those types of bottles.

In many cases, the diamond mark is embossed “LYRIC”. Illinois Glass Company had a very large manufacturing facility at Alton, IL, with over a thousand employees working there during the heyday of its operation.

Other glass manufacturing plants that were purchased by, and became part of Illinois Glass Company during its operation include the Thompson Bottle Company of Gas City, Indiana (acquired 1913) ; Chicago Heights Glass Company, Chicago Heights, Illinois (1913) , and Cumberland Glass Manufacturing Company of Bridgeton, New Jersey (1920). plants (at Los Angeles and San Francisco, CA) were organized as a wholly-owned subsidiary of Illinois Glass in 1902.

(See IPG and IPGCO marks on this page.) In 1929, Illinois Glass merged with Owens Bottle Company of Toledo, Ohio to form the Owens-Illinois Glass Company.

There are also many bottles known with a number or number/letter combination within a diamond.

These are also products of Illinois Glass Company, and some of the these numbers have been matched up with bottle style listings in early trade catalogs published by Illinois.During the earlier years, many of their bottles carried an “I. CO.” mark, and later an “I G CO inside a diamond” logo. This “Diamond I” mark was used by Illinois Glass from 1915 up to 1929, and is seen on many antique and vintage glass bottles.ABM (Automatic bottle machine) production was begun at Illinois Glass in 1910, and although it seems more likely (to me) the “I in a diamond” trademark would have been first used around that time, the U. Patent & Trademark Office data indicates Illinois Glass Company actually claimed use of this particular trademark began in 1915.Although there is probably no way to prove it, I suspect that some bottles made between 19 might carry the “Diamond/I” mark, but I may be wrong about that.Diamond-I mark " data-medium-file="https:// data-large-file="https:// class="wp-image-1232 size-medium" title=""Diamond I" mark used by Illinois Glass Company, on bottom of bottle" src="https:// alt="Diamond-I mark" width="300" height="158" srcset="https:// https:// sizes="(max-width: 300px) 100vw, 300px" / The “I in a diamond” mark is seen on HUGE numbers of containers.The “I” is sometimes misinterpreted as the “number 1”, and often does looks quite like a numeral “one” on some examples.
