The production process of bone china

As a high-end porcelain bone china, a large part of the reason for its high-end quality is that its production process is relatively complicated and it is not easy to mass-produce. What is the production process of bone china? What are the precautions for the production process? Below, the editor will give you a popular science about the production process of bone china. 1. The first thing is to match the raw materials. When we make any porcelain, we must first prepare the raw materials before we can make it. The raw materials needed to make bone china are mainly feldspar and clay, as well as the ashes of cattle from which impurities are removed. After the materials are prepared, they are matched according to a certain ratio and put into a ball mill for grinding, and then mixed with a mixer, so that the raw materials for making bone china are basically ready. 2. The second is to make a model. Model making is an important part of firing porcelain. It is related to the appearance of the next step of porcelain. Model making can be made by machine or artificial methods. Care must be taken in the process of making. Therefore, it is affected by the proportion of bone china cup raw materials. Influence, the viscosity of the model produced is not very large, and the model production has certain difficulties compared with other porcelains, so we need to pay attention to it. 3. Finally, the porcelain is fired. This is the most critical step in the production of bone china cups. Generally, it can be divided into two steps, one is high-temperature biscuit firing and low-temperature glaze firing. The temperature and time during the two-step firing process must be controlled well. A slight leak can easily lead to porcelain. Explosion, generally the high temperature should be controlled at about 1250 degrees Celsius, and the low temperature should be controlled at about 1150 degrees Celsius. After firing, it can be classified according to the fineness of the fired porcelain white porcelin dinnerware, and then through strict inspections by relevant agencies, it can enter the market or be sold with a proprietary logo.
