Ceramic tableware, the traditional concept of ceramics refers to all artificial industrial products made of inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or mixtures containing clay by mixing, forming and calcining. From rough earthware to fine fine pottery and porcelain ware all belong to its scope. Its main raw materials are silicate minerals (such as clay, feldspar, quartz, etc.) taken from nature, so it belongs to the category of "silicate industry" with glass, cement, enamel, refractory materials and other industries. The firing and application of ceramic tableware has a long history in our country. Its shape is diverse, colorful, cool and smooth, easy to wash, and is deeply loved by people. The production methods of ceramic tableware are divided into three types: overglaze color, underglaze color and mid-glaze color. Overglaze color ceramics are made of paint paper and pasted on the glaze surface or directly painted on the surface of the product with paint, and then baked at low temperature. Because the baking temperature cannot reach the degree of melting of the glaze layer, the flower surface cannot sink into the glaze. Touch the glaze color ceramics by hand, feel that the flower surface has obvious concave and convex feeling; the baking temperature of the glaze color ceramics can melt the glaze, the pigment can sink into the glaze, and it is covered by the glaze layer after cooling, the surface of the product is smooth, and there is no obvious concave and convex feeling; all the underglaze color ceramics are decorated on the porcelain blank, and after glazing, the flower surface is covered by the glaze layer, which looks bright, flat, and feels smooth.
