Porcelain is a white, hard, nonporous pottery which is resonant when struck. It was first made by the Chinese to withstand the great heat generated in certain parts of their kilns. The two natural substances used were kaolin and a feldspar mineral called petuntse that forms a glassy cement. In Europe porcelain was first commercially produced in the early 1700s.
