ca. 1956. Kaiser Aluminum plant. The new 420 foot potline at the Tacoma reduction plant; the result of a $2,000,000 expansion. 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)
