4. Han-notable for its concentration on organized ceramic production. Molds aided tremendously in the manufacture of identical vessels, but the most important technical innovation was the development of lead glazing. These low-fired glazes were colored with copper to produce green, or iron to create yellow or brown. The toxicity of lead however meant that these new glazes were best suited to mortuary pottery rather than daily use. Yueh refers to all southern high-fired celadon wares dating from as early as the Warring States period (480 - 221 B.C.) to the early Sung dynasty (10th century). Celadon is a descriptive term used primarily in the West to describe green glaze porcelaineous wares. Produced with iron oxide as the coloring agent and fired in a reduction atmosphere over 1200oC, Yueh celadon in fact can range from yellow to grey-green, olive, blue, or blue-green, depending on its glaze compound and conditions of firing. T'ang-They invented porcelain, underglaze painted décor, phosphatic glazes, perfected high-fired celadon, and experimented with cobalt blue glazes. Their interest in single color wares, especially white ware, brown ware, celadon, and cobalt blue laid the groundwork for Sung (960-1279) taste in monochrome glazes, refined ceramic shapes, and splashed brown and black wares. Sung-During the Sung period, a unity of the essential components fundamental to the art: vessel shape, potting techniques, glaze, decoration, firing processes, and aesthetic theory were all combined in a high standard of excellence.
