3000-year-old ceramic molding technique

The history of making porcelain in my country can be traced back to more than 3,000 years ago. There are many differences between chinaware ceramic and porcelain white porcelin dinnerware, but the two are organically linked. Ceramic craftsmanship was invented on the basis of the continuous development of ceramic art. Although porcelain white porcelin dinnerware is made of porcelain clay and has a glassy glaze applied on the surface, it still needs to be fired at a high temperature above 1000°C. But as a porcelain carcass, the molding method is basically the same as that of Tao ware. The ceramic cup custom manufacturer tells you that it has developed from the early manual kneading method and the clay stick disc construction method to the mud piece encircling method, wheel molding method, and printing method. Molding method, grouting method, etc. 1. Hand-made method: Do whatever you want with your hands to knead out some smaller objects. This is a primitive and simple method. 2. The clay stick construction method: knead the soil into clay sticks, build the clay sticks into the wall from the bottom of the device from the bottom to the top of the device, use the mud to bond the grinder, and leave it when the wall of the leveler is built Mud cracks. This method appeared in the middle of the Neolithic Age. 3. Mud piece enclosing method: the required raw material mud pieces are first processed into mud pieces, and then the mud pieces are enclosed and combined into the required shape. 4. Wheel forming method: Put mud on the wheel and use the centrifugal force generated by the wheel to form. It is mainly used for the production of round objects. The wheel system is divided into slow wheel and fast wheel. 5. Impression method: insert the mud into a special mold for forming. Mainly used to make ceramic figurines, animal and utensil parts, decorations, etc. 6. Grouting method: The method of pouring mud into plaster and other molds, using the capillary effect of the plaster mold to absorb the floating slurry on the inner wall of the mold to form. Square products, flat plates and inner surface relief products generally use plastic pressure. Plastic pressure is generally operated by two people at the same time. The whole process includes cutting mud, discharging mud, pumping air, tearing, receiving blanks, scrubbing, repairing edges, and displaying. Dispose of mold drainage regularly. The handle of the cup and most special-shaped products need to use the grouting process. Grouting is more troublesome than rolling and plastic pressing, and the cost is also higher. But at the same time, the value of special-shaped products is generally higher. Grouting includes the processes of grouting, pouring, reversing the mold, ejecting the mold, and finishing the mold.
