Permanente. The white, powdery alumina was discharged from bins into electrolytic cells known as reduction pots where it was periodically stirred. After heating in the reduction pots the molten aluminum was siphoned from the pots into 1 1/2 ton ladles. The ladles would be transferred by crane to the end of the potroom buildings where the molten metal was poured into molds forming pigs weighing 50 to 1,000 pounds.

The Pacific Northwest offered Permanente Metals, the producers of Kaiser aluminum, inexpensive hydro-electric power. In order to produce one pound of aluminum approximately 10 kilowatts of electricity is needed, therefore the Northwest is the ideal location for the Tacoma and Mead, near Spokane, plants. Interior view of the pot room, the white powdery substance is alumina, which is discharged into the reduction pots, the molten aluminum is siphoned from the pots into one and a half ton ladles (PMC Annual Report, 1947-1948).

Permanente Metals took over the Olin Aluminum facilities, that had shut down in November 1945, these facilities had not been in use until now. Kaiser bought the plant from the United States War Assets Administration, they then invested over one million dollars to modernize the plant. The Tacoma plant featured many self cleaning machines and a knowledgeable staff (T. Times, 10/31/47, p. 1).

This equipment is able to automatically wash away the fumes that are given off in the reduction process. The system consists of individual collectors connected to each pot and several washing stations. Permanente staff can be seen in the center area of the reduction plant.

Leo Olsen lost the use of his legs to infantile paralysis when he was 9 years old, but he was determined to be part of WWII. Although a tailor by trade, and a pianist, he found work at the Olin Coporation aluminum plant, on the tide flats, running one of the giant cranes that towered over the electric furnaces. This photograph of Mr. Olsen at the controls of his crane was taken in June of 1944 for the Tacoma Chamber of Commerce. (T. Times, 6/27/44, p. 2).

Kaiser Aluminum & Chemical Corp. At Kaiser's Tacoma reduction plant, ore is carefully analyzed. Dick Hildebrandt, plant chemist, performs an analysis of petroleum pitch, used in the production of carbon anodes for the electrolytic aluminum reduction process. One of the plant's largest regional purchases in 1954 was $214,000 worth of petroleum pitch. (TNT 5/16/1955, pg. 11)

Kaiser Aluminum; Arc building, looking southeast. The Kaiser Aluminum plant was located about 5 miles north of downtown Tacoma. It had been obtained in 1947 by the huge Kaiser business conglomerate built by Henry J. Kaiser. It was purchased from the Defense Plant Corporation. Kaiser modernized the closed plant and began a series of expansions. In 1956, a $2,000,000 expansion was complete with the creation of 18 new "super size" reduction cells. The improvement also included the erection of a mill-type building to house the 420 ft. potline, office and laboratory buildings, an added electric substation and installation of aluminum bus bars and auxiliary electrical equipment.

This new 420 foot potline at the Tacoma plant has 18 "super-size" reduction cells, increasing primary aluminum production by 15%. The Tacoma plant is a reduction plant, it uses power from hydro electric sources to reduce alumina to aluminum. In 1947, Kaiser bought the Tacoma plant from the Defense Plant Corporation which had operated it as a war emergency plant and closed it after VJ day. Its proximity to plentiful electric power, supplied by the Bonneville Power Administration, made it the perfect location for creating aluminum "pigs" by electrolysis. The plant on the Tideflats ran on a 24 hour, around the clock basis. (Kaiser Aluminum News, August 1956)

It produced the pig aluminum from treated ore. Each "pig" weighs 50 pounds and contains higher that 99% pure aluminum. The Bonneville Power Administration provided the abundant power needed to produce the metal by electrolysis. (Kaiser Aluminum News, August 1956)

The line contains 18 new "super size" reduction cells that will increase aluminum production by 15%. The Bonneville Power Administration will provide the power to reduce the ore to pure metal by electrolysis. Dissolved in solution in long lines of reduction cells ("pots",) alumina ore is subjected to electrical current. The chemicals recombine, the aluminum separates from the oxygen and settles as pure metal, aluminum. (Kaiser Aluminum News, August 1956)

Kaiser Aluminum, Tacoma Works rectifier station addition. Exterior of building with train tracks beside it. The Kaiser plants were taken over from the federal government in 1947 by Henry J. Kaiser. The plant in Tacoma was an aluminum reduction plant; it produced pig aluminum from treated ore and then sent it to a fabricating plant to be made into a finished product. The plant underwent a expansion and modernization program in 1952, at a cost of $2,850,000, to increase capacity by 1/3, an annual production of 66, 400,000 pounds.

Kaiser Aluminum's Tacoma plant near the southeasterly edge of Tacoma's tideflats was expanded at a cost of $2,850,000 in 1952, increasing by one third the plant's aluminum output. November 1952 marked the fifth anniversary of the operation of the Tacoma plant. Four alumina storage towers are seen in front of the plant facilities. Mount Rainier is seen rising majestically over the Tacoma tideflats. (TNT Supplement, 11/2/1952, p.3) TPL-9617

Storage tanks at Kaiser Aluminum are massive in nature; they dwarf the Canadian National Railroad boxcars that are motionless in front of them. Olin Corporation Aluminum Plant was the first occupant of the 3400 Taylor Way site; it was sold to Kaiser Aluminum in late 1946. Kaiser spent nearly three million dollars in 1952 to expand its plant, thereby increasing aluminum production accordingly. Easy access to rail transportation made delivery of its product fast and efficient. Photograph ordered by Kaiser Aluminum.

On October 27, 1948, Permanente Metal Corporation employees, left to right, Charlotte Thorestad, C.P. (Pat) Love (plant manager) and Darlene O'Brien sat surrounded by a sea of iced cupcakes marked with a "P" and decorated with a single candle. Permanente's aluminum reduction plant at 2400 Taylor Way was celebrating its first year of production of Kaiser Aluminum with a "Family Day" Open House. Employees along with 1,500 friends, families and relations were the guests of management. They observed the step by step process of making aluminum and ate hot dogs cooked on a 500 lb. "pig" of aluminum, sandwiches, cupcakes and punch. The plant had been previously operated during World War II by the Olin Corporation. After its purchase by Kaiser, it became one of six aluminum plants operated by the company. The other plants were located at Mead and Trentwood Washington (near Spokane), Baton Rouge La., Newark Ohio and San Jose Ca. The Tacoma plant was permanently closed in 2002 and later demolished.

Permanente. Two men are having fun with a load of alumina, a fine white powder that is refined from alumium-bearing ore, bauxite. Bauxite was mined in South America, refined, using the Bayer process, in Baton Bouge and shipped by rail to the Pacific Northwest where it was converted into primary aluminum. Four pounds of bauxite were required to obtain two pounds of alumina shich yields one pound of aluminum. As of September 1948 nearly 500 boxcar loads of alumina per month were brought to Tacoma and Mead aluminum reduction plants, thereby becoming one of the largest users of boxcars in the Northwest.(Permanente Metals Corporation 1947-1948 Annual Report; T.Times, 9/6/1948, p.12)

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).
