Enamel porcelain was an extremely valuable imperial utensil in the Kangxi, Yongzheng and Qianlong dynasties of the Qing Dynasty. It is a new product created by the fusion of traditional Chinese porcelain making techniques and enamel painting techniques inherited from France. Colored porcelain varieties. Enamel porcelain was created and fired during the Kangxi period and flourished during the Yongzheng and Qianlong periods. Pastel porcelain appeared in the late Kangxi period and flourished during the Yongzheng and Qianlong periods. Pastel porcelain is also called soft-colored porcelain. It is one of the four traditional famous porcelains of Jingdezhen Kiln. A variety of porcelain with pastel as the main decorative technique. Pastel is a painting method in which overglaze (on porcelain body) is painted at low temperature and fired. Pastel porcelain is a new variety of overglaze color created on the basis of five-color porcelain in the late Kangxi period of the Qing Dynasty and influenced by the production process of enamel porcelain. It was created and fired in the late Kangxi period and has remained popular in subsequent dynasties. This article mainly discusses the differences between enamel and pastel utensils of this period. The difference between the two should be mainly analyzed from several aspects such as color materials, patterns, and styles.
From the perspective of the color material itself, the enamel color material contains a large amount of boron, and the matrix is lead, boron, and glass frit, while the pastel material does not contain boron, and the matrix is glass powdered emulsion containing potassium oxide. It is unrealistic to judge whether an artifact is enamel or pastel based on this, because it is impossible to extract color material samples from the artifact to test whether it contains boron, but the two color materials contain different components. Reflecting different surface forms, we can use this difference to analyze whether an artifact belongs to enamel or pastel. Since the matrix of the enamel color material contains glass frit, the surface morphology of the enamel color material has a strong glass texture and the color material has good transparency. Of course, there are also special circumstances. During the Kangxi period, powder was sometimes added to the color materials, so the color materials were opaque. However, during the Yongzheng period, powder was not added to the color materials, so the color materials had a strong glass texture and bright colors. ,Structured. The matrix in the pastel material is glass powdered emulsion containing potassium oxide, so its surface morphology has a weak glass texture, and the color material has a strong opacification and opacity.
The chemical composition of enamel and pastel. Enamel and pastel are made by adding different colored metal oxides to glass powder. Glass powder is the basic glaze, which is made by grinding glass. The main raw materials are quartz, feldspar, borax, fluoride, etc. mixed in appropriate proportions. The main function of color-forming metal oxides is to be mixed in the basic glaze to produce different color effects. It can be said that making various colored glazes is the same as adding different metal oxides to make colored glass when firing glass.
