Hazel-Atlas Glass Company
The Hazel-Atlas Glass Company was a large producer of machine-molded glass containers headquartered in Wheeling, West Virginia. It was founded in 1902 in Washington, Pennsylvania, as the merger of four companies:
- Hazel Glass and Metals Company (started in 1887)
- Atlas Glass Company (started 1896)
- Wheeling Metal Plant
- Republic Glass Company
By the 1930s, Hazel-Atlas had fifteen plants (plants included those in Clarksburg, WV; Zanesville, OH; Ada, OK; Montgomery, AL; Oakland, CA; Pomona, CA and other locations) and was the largest glass manufacturer in the world. Hazel-Atlas manufactured tremendous quantities of "depression" pressed glassware in a wide variety of patterns throughout the 1920s, '30s and '40s. They also produced many of the white milkglass "inserts" used inside zinc fruit jar lids, as well as many types of milkglass cold cream jars and salve containers. Also an important maker of a very large variety of bottles and jars for the commercial packaging industry. "Atlas" was the name brand of their most popular line of fruit jars for home canning. Hazel-Atlas, at that time the third largest producer of glass containers in the U.S.,became a subsidiary of the Continental Can Company in 1957. The acquisition was challenged under the Clayton Antitrust Act in a case that was eventually decided by the U.S. Supreme Court in United States v. Continental Can Co.. It continued to make containers, glassware and tableware into the 1960s. In 1964, 10 of the 12 H-A plants in operation were sold to Brockway Glass Company, and it is unclear if the remaining two plants used the H-A trademark after that year.
Hazel-Atlas produced dozens of different patterns, with unique names. The Hazel-Atlas mark, usually placed on the back of the product, is an "A" nestled underneath an "H". The mark was reportedly first used in 1923, according to trademark office records quoted by Peterson (400 Trademarks on Glass).
