The display of seven canisters of Flake Caustic Soda produced by the Pennsylvania Salt Manufacturing Company was taken on August 27, 1951. Flake Caustic Soda apparently was sold in several different size metal cans; only the smallest can has a handle for easy carrying. Caustic soda, also known as sodium hydroxide, is a white brittle solid used especially in making soap, oils, rayon and paper. It can also be in liquid or flake format, as in this particular display.

General American Evaporators shown in evaporator room at Pennsylvania Salt. Penn Salt began a $172,000 plant expansion program in March 1951. The biggest investment was to be in new equipment in the plant's chlorine and caustic soda departments. Some building modification was also included. The expansion was necessitated by both increased normal demands and those spurred by war production. (TNT, 3/30/1951)

Example of General American Evaporators in place at Pennsylvania Salt. Ordered by General American Transport Corp., NY, NY, Harold Jacoby. Capacity of the Tacoma plant for production of chlorine and caustic soda was being increased 30%. Pennsalt had been granted a federal certificate of necessity for $445,450. As of March 1951, power hearings brought out the fact that chlorine and caustic sodas were ranked among the top poriority defense items, being used in aircraft manufacture and at the Hanford A-bomb plant, as well as suppllying local chemical plants and domestic needs.

Several shots at plant to be used as mural at Poodle Dog, Penn Salt Manufacturing Co., Mr. Shanaman. Two workers check rows of tanks at Pennsylvania Salt Manufacturing Company. The company was a manufacturer of basic chemicals from salt including caustic soda, chlorine, sodium hypochlorite, hydrogen, dairy and poultry germicides, special chemical cleaners and dry cleaning products.

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.

ca. 1960. Pennsylvania Salt Manufacturing Co.'s 40-acre plant faced the Hylebos Waterway and portions of undeveloped Northeast Tacoma, including an enormous gravel pit. Aerial photographs taken by the Richards Studio in 1960 show the large facility along with numerous storage tanks. A ship is docked ready to be loaded with the company's chemical products.

This aerial view of Pennsylvania Salt Manufacturing Company shows their building complex, 2901 Taylor Way, as it appeared in July 1956. Storage tanks dot the area around the plant and one of the Pennwalt barges can be seen being maneuvered to the dock by two tugs. In 1928, the eastern firm was invited to build a caustic soda and liquid chlorine plant on 14 acres of filled ground adjacent to the Hylebos Waterway. The plant opened the following year as Tacoma ElectroChemical Company. As the parent firm diversified the plants' chemical production, it became known as Pennsalt, and then Pennwalt. Pennwalt Corp. was taken over by Elf-Atochem in 1990. ("South on the Sound" by Murray Morgan)

Aerial view of Pennsylvania Salt Manufacturing Co. Storage tanks dot the area around the plant and one of the Pennwalt barges can be seen being maneuvered to the dock by two tugs. The large corporation, now known as Pennwalt, had its beginnings in 1850 when five Philadelphia Quakers organized the Pennsylvania Salt Manufacturing Co. and constructed a plant to produce lye and alkaline salts of soda from natural salt. Today Pennwalt, with its headquarters in Philadelphia, is a worldwide manufacturer of chemicals, health products and precision equipment. The chlorine produced by the company is used in paper and pulp manufacturing, but also in water purification, bleach and the manufacture of adhesives. Caustic soda is also used in pulp production.
