Philadelphia Quartz Co. gets sodium silicate, derived from silica sand, shipped here to their plant, they then manufacture silicate of soda in its various forms. They are the main suppliers of liquid mineral adhesives for the plywood and composition industries. Exterior view of the plant's liquid storage tanks and office buildings.

An aerial view of Philadelphia Quartz' plant on the Tacoma tideflats. Philadelphia Quartz, with its plants in Berkeley, Los Angeles and Tacoma, was the leading producer of soluble silicates. Its products were used in paper mills, soaps, detergents, high octane gasoline, plywood, corrugated boxes and television sets. Silicates were the unknown product that made modern conveniences possible.

The company had plants in Berkeley, Los Angeles and Tacoma. The silicates were components of the adhesives used in plywood production and corrugated paper board for the container industry. They were used in city and industrial waterways to clarify raw and waste water and stop rusting.

Philadelphia Quartz Company, established in 1942, was the only sodium silicate plant in the Tacoma area. Belgian silica sand and California soda ash were chemically combined to obtain the product sold largely in Tacoma but marketed also in other Northwest cities. Silicate of soda, water-glass to farm households, was used in adhesives for the plywood industry and corrugated paper-board for the container industry. Televisions of the time required potassium silicates to produce the phosphor screen in the picture tubes. Philadelphia Quartz was headquartered in Berkeley, California.
