Yongzheng Dynasty, although only 13 years ago, but the process of making porcelain has developed to a new level in history. On the basis of inheriting the ceramic technology of Kangxi Dynasty, the blue and white porcelain of this period had many innovations, changes and improvements. The official kiln blue and white of Yongzheng Dynasty approached the porcelain of Kangxi Dynasty in the early period, and some of them were bright and bright in color. In the mid-term, it has the characteristics of this dynasty. Blue and white tones are dark. Some of the imitation Xuande blue and white porcelain are dizzy and scattered. There are small black spots artificially dotted on the decoration, which have no metallic luster and do not sink into the body. Some of the imitation Jiajing and Wanli blue and white porcelain are dark blue and stable in color. Some of them imitate the blue and white porcelains of the time of transformation, and their colours are light and grayish.
The body of this blue-and-white porcelain from Yongzheng official kiln is firm, white, fine, light and thin. Its outer wall and sole are treated irregularly and its shape is handsome. It is very outstanding in Qing Dynasty porcelain. The fetal wall is thin and hard, with a high degree of ceramization. It taps gently with its fingers to make a crisp metal sound. Tire repair meticulous, can not see scratches. The high-grade porcelain of civil kiln is basically similar to that of official kiln. It is difficult to find the uncrushed ceramic stone particles, even if there are some, which are very small.
