Bricks were produced in November 2011 by the Belden Brick Company in Canton, Ohio. These were shipped to Puerto Rico to be crushed. The fireclay, “Brookville Clay,” is considered to be a coal-formation clay. Major components are silica (about 26-27%) and alumina (58-59%). XRD identified quartz, microline, and dehydroxylated muscovite.
