Scope and content
The Tacoma plant of the Permanente Metals Corporation accomplished its first casting of "pigs" from molten metal in November of 1947. Plant employees in the pot room were photographed getting the newly molten metal in the ladle ready to pour into a mold to form pigs. Cast pigs could weigh from fifty and one thousand pounds depending on size and composition. Once cooled, the pigs were stacked on pallets and transported to the rolling mill at Trentwood, located near Spokane, Washington. The pigs from the Mead and Tacoma plant would later be re-melted in furnaces where other metallic elements were added to form standard alloys. Tacoma's Permanente plant produced aluminum in commercial quantities for Henry J. Kaiser's industrial operations. (PMC Annual Report, 1947-1948; T.Times 11-19-47, p. 18-alt. photograph & article).
