Do you make the craftsmanship characteristics of bone china tableware? 1. Secondary firing process Bone porcelain tableware 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 tableware is different from the traditional low-temperature biscuit firing and high-temperature glaze firing of traditional ceramics, and it better solves 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 'bisqueThis burn'. 2. The forming process bone china uses 40%-50% non-plasticity bone powder. The total amount of clay in the green body formulation is low, and the plasticity is poor compared with ordinary ceramics, and it is more difficult to form. 3. The firing process The use of imitation saggers is the most representative process in the firing process of Porcelain Dinnerware Set. Because the firing range of bone china is narrow, the shrinkage is large, and it is easy to be deformed during firing, so buckle firing must be used. , Support mouth burning or buried burning process to solve the deformation problem. 4. Kiln furniture materials Bone porcelain tableware tableware 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 high production cost and is generally suitable for making high-end porcelain tableware. The carcass is required to be thin. Therefore, the mold requirements are more stringent. 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 bone china white porcelin dinnerware is white and delicate, and any small dirty spots are particularly dazzling. To produce high-grade bone china tableware, strict and meticulous production management must be carried out to ensure product quality.
