In many ceramic production processes, it is necessary to color ceramics, and many manufacturers have previously used ceramic pigments. Ceramic pigments refer to mixtures of powdered metal oxides and other materials used in ceramic glaze, used for decorating ceramics, porcelain, and red pottery, as well as in ceramic enamel for decorating metal ware. When it is in powder form, most ceramic pigments are gray white; When works are calcined in ceramic kilns or kilns, their rich and vibrant colors will appear.

Due to the development of modern technology, many high-end ceramics now use ceramic ink. Ceramic ink refers to ink containing certain ceramic glaze components, ceramic pigments, or ceramic colorants. The composition and functionality of ceramic ink are related to the working principle of the printer and the purpose of the ink. Ceramic ink is composed of inorganic non-metallic pigments (pigments, glazes), solvents, dispersants, binders, surfactants, and other auxiliary materials. Inorganic non-metallic pigments are the core substance of ink, with standard particles smaller than 1 micron, narrow particle size distribution, and no strong agglomeration between particles. They have good stability and are less affected by solvent substances.

Whether it is ceramic pigments or ceramic inks, the presence of grinding machines is necessary in the production process. Generally speaking, ceramic pigments and ceramic inks. After mixing, calcining, and washing the raw materials, a crushing process is required. After washing with water, use a disc mill or ball mill to grind the required fineness using a wet method. Although there is no explicit requirement for the particle size of the pigment, it is generally required to pass through a 300 mesh sieve. When the pulverization is insufficient, it will be difficult to use due to uneven particle size, and the lack of covering force will cause spots to form after firing. On the contrary, if the crushing is too fine as dust, it cannot fully fuse in the glaze and become the cause of glaze rolling.
