“B in a circle” mark on bottles: Brockway Glass Company, Brockway, Pennsylvania (1907-1988)
This mark was adopted by Brockway Glass Company in 1925 and used on tremendous numbers of bottles, up until circa 1988.
The “B in a circle” mark is usually seen on the base, and seems to have been placed in the center of the base on most earlier bottles (I don’t have a timeline to indicate HOW early), but by the late 1970s, if not earlier, the “B” was typically placed near the top, as in the 12:00 position on a clock. (See pics below of late 1970s-early 1980s bottles). However, keep in mind that this typical placement of the mark is not 100% consistent, and some bottles made by Brockway might not conform to this general rule.
Brockway Machine Bottle Company (starting in 1907) merged with its own subsidiary Broadway Sales Company (created 1927) to form Brockway Glass Company in 1933. In 1933, Brockway bought the Monaca Glass Company, Monaca, Pennsylvania, but closed that plant about a year later.
Other glass plant acquisitions included the former De Camp Consolidated Glass Casket Company (Muskogee, OK) in 1946; Sterling Glass Company (Lapel, Indiana) in 1950; the Demuth Glass Company of Parkersburg, WV in 1955, and the Tygart Valley Glass Company, Washington, PA, in 1959. In 1964, 8 of 10 Hazel-Atlas Glass Company glass manufacturing plants were acquired by Brockway, bringing the total number of plants at that time to sixteen (Julian Toulouse, Bottle Makers and their Marks, 1971, pages 60-61).
In the year 1973, (besides the Brockway PA location), their glass factories were located at: Crenshaw, PA; Muskogee, OK; Lapel, IN; Freehold, NJ; Parkersburg, WV; Washington, PA (2 plants); Rosemount, MN; Zanesville, OH; Montgomery, AL; Ada, OK; Oakland, CA and Pomona, CA.
In 1988, Brockway Glass Company assets were purchased by Owens-Illinois, Inc., forming Owens-Brockway, Inc., now Owens-Brockway Glass Containers, Inc. Exact corporate structure seems a bit confusing to me, but Owens-Brockway Containers, Inc., is presently (2013) a subsidiary of Owens-Illinois, Inc., with O-I corporation headquarters (formerly based in Toledo, OH) now (since 2006) based in Perrysburg, Ohio.
Many of the former Brockway Glass Company container plants are still in operation, under the Owens-Brockway Containers Inc. name. (See my page that pictures Owens-Illinois Glass Company marks).
