Description

Technical Field

[0001] The invention relates to the technical field of ceramic materials, and in particular to a ceramic decorative flower mud and a preparation method and application thereof. Background Art

[0002] Liling pottery making began in the Eastern Han Dynasty, but the creation of Liling underglaze colored porcelain began in the late Qing Dynasty. The production process of Liling underglaze colored porcelain is very complicated. First, the pattern is painted on the semi-finished blank, and then glazed and fired in a high-temperature kiln at 1380℃. Among them, painting is a key link, which requires craftsmen to have superb painting skills and rich experience. The special thing about Liling underglaze colored porcelain is that it also uses the unique technique of "double hook and water separation" in traditional Chinese painting, that is, the lines are drawn with ink during painting, and then the ink evaporates after high-temperature firing, and finally becomes a smooth blank on the glaze surface. This technique makes the lines of the patterns on the porcelain smooth and the colors distinct. Liling underglaze colored porcelain has delicate porcelain, exquisite patterns, and colorful colors. The glaze surface is crystal clear and moist, and the water is transparent. It looks lifelike under the glaze layer. Its colors are rich, and the multi-level color gradations show strong artistic expression and appeal, perfectly presenting the traditional painting art on porcelain. Liling underglaze colored porcelain is not only an important part of Chinese ceramic art, but also an important carrier of Chinese culture. It has attracted ceramic enthusiasts and collectors from all over the world with its unique artistic charm, and has become an important bridge for cultural exchanges between China and foreign countries.

[0003] At present, the artistic decoration methods of Liling art porcelain mainly include painting, sculpture carving, and colored glaze decoration. However, the existing artistic decoration of Liling art porcelain has the limitations of single decorative effect and lack of three-dimensional sense. Summary of the invention
