Description

Technical Field

[0001] The invention belongs to the technical field of kiln-changed glaze porcelain production, and in particular relates to a kiln-changed glaze porcelain coloring method. Background Art

[0002] The coloring of kiln-changed glaze porcelain is the use of kiln-changed glaze techniques in the production process of porcelain. Through special kiln-changed glaze formulas and firing processes, the glaze surface presents different color effects. The uniqueness of this technique is that the color change occurs naturally during high-temperature firing, rather than applying pigments or colorants to the glaze surface. This effect is loved by people because of its contingency and uniqueness. The following is a summary of the characteristics of kiln-changed glaze porcelain: 1) The glaze color changes are varied: the glaze color change of kiln-changed glaze porcelain is its significant feature. 2) The glaze gloss and texture are unique: the glaze gloss and texture of kiln-changed glaze porcelain are also its important characteristics. 3) The glaze texture and bubble distribution vary: the glaze texture and bubble distribution of kiln-changed glaze porcelain of different ages are also different. 4) The thickness and transparency of the glaze layer are different: the early kiln-changed glaze porcelain, such as the Northern Song Dynasty Jun porcelain, has a thick and milky glaze layer, which is opaque or translucent. 5) Complex production process: The production process of kiln-changed glaze porcelain is relatively complex. Because the required glaze layer is thick, it needs to be glazed many times, and each glaze must be dried before the next glaze blowing. During the firing process, the temperature and atmosphere need to be controlled to make the glaze color change naturally and colorful.
