After the invention of pottery in the Neolithic period, (5000-2200 B.C.), the ancient Chinese succeeded in producing painted pottery, black pottery and carved pottery. The major contribution made by Tang dynasty (616-906 A.D.) potters was their bold introduction of the multi-colour wares. Chinese ceramic ware is an art form that has been developing since the dynastic periods. The first types of ceramics were made about ten to eleven thousand years ago. Chinese ceramics range from construction materials such as bricks and tiles, to hand-built pottery vessels fired in bonfires or kiln, to the sophisticated porcelain wares made for the imperial court.
