How much do you know about the 6 major technological characteristics of bone china white porcelin dinnerware? 1. Secondary firing process The history of bone china is a typical representative of soft porcelain. The second firing process of high-temperature biscuit firing and low-temperature glaze firing is its most significant process feature. The secondary firing process of bone china is different from the traditional low-temperature bisque firing and high-temperature glaze firing of traditional ceramics. It can better solve the problems of high temperature deformation and glaze gloss. The Japanese call the body that cannot be glazed at low temperature (about 900°C) is called 'biscuitThis burn'. 2. The forming process Porcelain Dinnerware Set uses 40%-50% non-plasticity bone powder. The total amount of clay in the green body formula is low, and the plasticity is poorer than ordinary ceramics, and the forming is more difficult. 3. The firing process The use of imitation saggers is the most representative process in the bone china firing process. Because the firing range of bone china is narrow, the shrinkage is large, and it is easy to deform the bed during firing, so buckle firing, Processes such as bracing or burial firing can solve the deformation problem. 4. Kiln furniture materials Bone porcelain white porcelin dinnerware uses kiln furniture materials that have higher requirements than general chinaware ceramic. Most kiln furniture must match the product. Generally, each type of product has a matching kiln furniture. This is where the production of bone china is more cumbersome than the production of general ceramics. The bone china production team has a large demand for kiln furniture materials, and the requirements for the working surface of the kiln furniture products are quite high. 5. The mold material bone china has a relatively high production cost and is generally suitable for making high-end porcelain white porcelin dinnerware. The carcass is required to be thin. Therefore, the mold requirements are stricter. It is necessary to use high-quality gypsum for fine processing and production, and the use of the mold must be strictly controlled, and the mold cannot be used for a long time. 6. Production management The material of Porcelain Dinnerware Set is white and delicate, and any small dirty spots are particularly dazzling. To produce high-grade porcelain tableware, strict and meticulous production management must be carried out to ensure product quality.
