Iron oxide production began at the facility in the 1876, under the name C.K. Williams Company. In the 1920s, the company began production of synthetic iron oxide pigments using pickle liquor and scrap metal. The facility was purchased by Pfizer, Inc. in 1962 and in 1984 the corporate entity that owned and operated the plant was incorporated as Pfizer Pigments, Inc., a subsidiary of Pfizer, Inc. Magnetic oxide production began in the early 1970s. In the spring of 1990, Pfizer Pigments, Inc. sold the portion of the plant west of the Bushkill Creek (approximately 100 acres) to Harcros Pigments, Inc., which was a subsidiary of Harcros, Inc.. In January of 1998, Elementis purchased the site from Harcros Pigments. The site is currently owned and operated by Elementis.
Currently, Elementis manufactures iron oxide pigments of various colors and grades at its Easton plant. Sulfuric acid is used in this process to create a ferrous sulfate solution, which is then processed into a final product.
