The abundant clay in and around Palo Pinto County was recognized around the turn of the 20th century as a source of raw material for brick manufacturing. Rejected fine coal from the area’s coal mines furnished heat to fire the clay and bake it into brick. The brick factory in far western Parker County, near the Rock Creek coal mine, was a major industry in Mineral Wells for many years. Area bricks were used to build the seawall at Galveston after the disastrous hurricane of 1900, to pave both the highway from Mineral Wells to Ft. Worth as well as many of the streets in Tarrant County. The plant also produced the bricks used to pave Congress Avenue in Austin.
