Hazel-Atlas Glass Company

It was founded in 1902 in Washington, Pennsylvania,[1] as the merger of four companies: By the 1900s, Hazel-Atlas was a large glass maker, with 15 plants, including ones in Ada, Oklahoma; Clarksburg, West Virginia; Montgomery, Alabama; Oakland, California; Pomona, California and Zanesville, Ohio.

[1] Hazel-Atlas made large quantities of "Depression" pressed glassware in a wide variety of patterns in the 1920s–1940s, along with many white milkglass "inserts" used in zinc fruit-jar lids, many types of milkglass cold-cream jars and salve containers, and a large variety of bottles and jars for the commercial packaging industry.

"Atlas" was the brand of the company's most popular line of fruit jars for home canning.

Hazel-Atlas—then the third largest producer of glass containers in the United States, with almost ten percent of the market[2]—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..
