“Because of the numerous processing required in manufacture, brick was a highly transformed material, perhaps the most “artificial” of all building materials available to many builders. Bricks vary slightly in size, but most average around 8¼ inches on the long face, 4¼ inches on the short end, and 2¼ inches high; they are designed to be small enough to be handled by one person.”
