THE USES OF CHINA Owing to its acid and heat resisting properties china finds a special use in chemical industries. It will often be found in large industrial concerns where cleanliness is of great importance. It is even employed in grinding—porcelain balls pound materials in a cylindrical machine known as a "ball mill." Porcelain is also used for the linings of these mills.
It is a splendid material for insulating, and consequently is much used by the electrical industry. In Central Europe the bowls of tobacco pipes are composed of porcelain.
Its use in domestic ware is well known, while almost everyone possesses a dainty figure or some other piece of ornamental por celain. (See also POTTERIES AND PORCELAINS, EARTHENWARE.)
