Pennsalt; Plant & employees for magazine. As the western headquarters for Pennsylvania Salt, the Tacoma plant also employed a large office staff. This group may have been attached to the sales department. The chemicals produced at Pennsalt were sold mainly to pulp, paper, plywood and soap manufacturers.

Pennsylvania Salt Manufacturing Company. The exterior of one of the buildings at the plant. A flag pole stands in front of the building. The $2 million Tacoma plant covered about 40 acres of tideflats on Hylebos waterway. Their products included chlorine and caustic soda (used in pulp, paper, plywood and soap manufacture as well as for sanitation purposes), chemical manufacturing, metallurgical and other processes and herbicides.

This photograph of six cans of caustic soda manufactured by Pennsalt was taken on September 15, 1951. The black metallic cans are of various sizes; five of them contain flake caustic soda while the remaining container is labeled solid caustic soda. Caustic soda, also known as sodium hydroxide, is a white brittle solid used especially in making soap, rayon and paper. It can be in liquid, solid or flake form. The Pennsylvania Salt Manufacturing Co. had a large chemical plant in the Tideflats which manufactured basic chemicals from salt for pulp mills and then onto other products.

A small group of visitors stand in front of the Pennsylvania Salt Manufacturing Company of Washington's Taylor Way plant. Nearby is a tank used to contain liquid chlorine, one of Pennsalt's many chemical products. The company opened its doors for a celebration of its parent firm's 100th anniversary which included tours, demonstrations, and refreshments. (TNT 8-6-50, p. A-9)

A Pennsalt guide explains to interested visitors how caustic-chlorine is created during Pennsalt's 100th anniversary open house. Despite its name, Pennsalt does not produce ordinary table salt. It does, however, produce caustic and chlorine from coarse gray California salt for pulp mills. Brine flows into cylinders and caustic soda drains off at the bottom with chlorine gas emerging from the top. These chemical products are then shipped back to California by tanker for a profit.

Pennsylvania Salt Manufacturing Co. of Washington had its headquarters in Tacoma. Despite its name, Pennsalt did not produce table salt but instead was a basic manufacturer of chemicals from salt. It, along with Hooker Electrochemical, supplied caustic soda and chlorine to the Pacific Northwest's pulp and paper industry. View of some of the machinery used by Pennsalt in their Tideflats plant; these are believed to be rotary converters used to convert AC power to direct current.

Pennsylvania Salt Manufacturing Co. Family Day; employees' picnic and open house. An unidentified group of employees stands in front of a display case set up for the open house. Wives, husbands and children of employees were invited on this day to tour the plant. A brief program was devoted to safety measures practiced at the plant. Lunch for 300 employees and their visitors was followed by a tour of the plant. The manufacturing facility opened on the Tideflats in June of 1929 as Tacoma Electro-Chemical Co. Despite its deceptive name, Pennsalt manufactured industrial chemicals, some of which were used in the manufacture of pulp and paper. (TNT 9/6/1953, pg. A-12)
