In the Tang and Song Dynasties ,the low-temperature-glazing technique originated in the Han Dynasty had 
gradually developed into the glazing technique of the Tang tricolor ceramics . their glaze colors were mostly yellow , green white , and brown . Blue glaze color was rarer and more precious . The polychrome glaze was a great improvement on the monochrome glaze . Judging from the Tan tricolor figurines unearthed from the Tang tombs , their forms and glaze colors both showed a fairly high artistic level . The ceramic horses and ceramic camels were well proportioned , and he forms of their muscles conformed with anatomical results .
The Chinese pottery craft consummated in the Yuan , Ming and Qing Dynasties . The products in his period not only utilized all the experiences in applying blue and white glazes , but also developed the colored painting technology . The blue and white porcelain and the red underglaze porcelain were great inventions of the porcelain craftsmen of Jindezhen . The “pure sweet white 
porcelain” produced in the reign of Emperor Yongle of the Ming Dynasty eliminated the defects of the past white porcelain in cream of pale blue shades , providing a better condition for later colored painting on porcelain . In the Ming and Qing Dynasties , there were various color glazes , such as bright red , rainbow red , ruby red , crimson red , azure , sapphire blue , peacock blue , light yellow , fish-roe yellow , eel yellow , eggplant purple , etc . In the reign of Emperor Qianlong , there were as many as fifty seven colors . Gold coating on porcelain initiated in the Yuan Dynasty was developed further in the Ming and Qing Dynasties . In the Qing Dynasty the gold coating method for lacquer ware was adopted for the porcelain ware to create the “gold smearing” and “silver smearing” methods . The forms of porcelain ware in the Ming and Qing Dynasties were very varied and almost all – inclusive .
Apart from the world-famous Jindezhen pottery , China witnesses a host of ceramic reassures : the age long blue glazed porcelain of Longquan in Zhejiang province , the white glaze porcelain of Dehua in Fujian province , he red stoneware of Yixing in Jiangsu province , the thick color-glaze “jun” pottery in Taiwan and Guangdong , the embossed enamelware in Shanxi province , the painted black-glaze porcelain in Hebei and Henan provinces , the incised glaze earthenware of Jieshou in Anhui province , the crimson earthenware of Zibo in Shandong province , the green-glazed earthenware of Tongguan in Hunan province , the hollowed out glaze earthenware and plain earthenware of Congning and Rongchang in Sichan province , and the natural color earthenware of Jianshui in Yunnan province and Transship in Gansu province , all of which have their special styles and properties .
To sum up , Chinese porcelain articles are no only practical vessels , but also possess very high aesthetic value with regard to their forms , coloring and decorative art . They integrate perfectly practicality and aesthetics , technology and art .
