is characterized by use of the elm-like Japanese zelkova (keyaki 欅), powdered earth, and delicate features formed from cloth. (See the Japanese article, 輪島塗. A more complete list of regional lacquer traditions is available in the Japanese article.) Chinese lacquerware During the Shang dynasty (ca. 1600–1046 BC) of China, sophisticated lacquer process techniques developed became a highly artistic craft. During the Eastern Zhou period (771–256 BC), lacquerware began appearing in large quantity. This is the earliest era from which notable quantities of lacquerware have survived. At the time of the Han dynasty (206 BC – 220 AD), special administrations were established to organize and divide labor for the expanding lacquer production in China. Elaborate incised decorations were used in lacquerware during the Han dynasty. In the Tang dynasty (618–907), Chinese lacquerware saw a new style marked by the use of sheets of gold or silver made in various shapes, such as birds, animals, and flowers. The cut-outs were affixed onto the surface of the lacquerware, after which new layers of lacquer were applied, dried, and then ground away, so the surface could be polished to reveal the golden or silvery patterns beneath. This was done by a technique known as pingtuo. Such techniques were time-consuming and costly, but these lacquerware were considered highly refined. It was also the period when the earliest practice of carving lacquerware began. The art of inlaid gold, silver, and mother-of-pearl continued from the Tang into the Song dynasty (960–1279). Several existing decorative techniques gradually developed further after the 10th century, such as diaoqi (carved lacquer) which involves building up layers comprising thinly-applied coats of lacquer and carving it into a three-dimensional design; qiangjin (engraved gold) in which fine lines are incised, an adhesive of lacquer is applied, and gold foil or powder is pressed into the grooves; and diaotian or tianqi (filled-in) in which the lacquer is inlaid with lacquer of another color. A variation of diaotian or tianqi is known as moxian (polish-reveal) in which a design is built up with lacquer in certain areas, the remaining areas are filled with lacquer of a different color, and the entire surface is polished down. Especially the art of inlaying lacquer with mother-of-pearl was intensively developed during the Song dynasty. However, during the Song, the artistic craft also made use of inlaid gold in a process of which is to engrave intricate patterns in the lacquer
