Chinese ceramic ware shows a continuous development since imperial times and is one of the most significant forms of Chinese art and ceramics. The first types of ceramics were made during the Palaeolithic era. Chinese ceramics range from construction materials such as bricks and tiles, to hand-built pottery vessels fired in bonfires or kilns, to the sophisticated Chinese porcelain wares made for the imperial court. Porcelain is so identified with China that it is still called "china" in everyday English usage.
