Ceramic Mug Group,
The history of making porcelain in my country can be traced back to more than 3000 years ago. Although there are many differences between pottery and porcelain mugs
, the two are organically linked. Porcelain-making technology was invented on the basis of the continuous development of ceramic-making technology. Although porcelain is made of porcelain clay, the surface is covered with vitreous glaze, and it is baked at a high temperature above 1000 ℃. But as a porcelain carcass, the molding method is basically the same as that of Tao ware, from the earliest manual kneading method and clay stick disc construction method to the mud piece encircling method, wheel molding method, impression method, and grouting method. Wait.
1. Hand Kneading Method
Use your hands to create the clay as you like, pinch out some smaller objects, this is the most primitive and simplest forming method.
2. Clay stick plate construction method
Rub the soil into mud sticks, build the mud stick discs from the bottom to the mouth of the vessel from the bottom to the mouth, then glue the whole vessel with mud, and finally smooth out the mud cracks left by the wall of the vessel. This method appeared in the middle of the Neolithic Age.
3. Mud Piece Enclosing Method
The raw mud blocks are first processed into mud pieces, and then the mud pieces are enclosed and combined into the required shape.
4. Wheel forming method
A method in which mud is placed on the wheel and formed by the centrifugal force generated by the rotation of the wheel. It is mainly used for the production of round objects, and the wheels are divided into slow wheels and fast wheels.
5. Impression method
The method of inserting the mud into a special mold. Mainly used to make ceramic figurines, animal and utensil parts, patterns, etc.
6. Grouting method
A method of pouring mud into a mold such as plaster, and using the capillary action of the plaster model to adsorb the suspended slurry on the inner wall of the mold to form.
At present, China Ceramic Factories
uses three kinds of molding processes: rolling, plastic pressing, and grouting. Both rolling and plastic pressing belong to the impression method. These three types of molding methods are enough to control the changes in the shape of Tao Run's thousands of products.
Rolling is used in the production of circular, symmetrical, and embossed products on the outer surface.
Square products, flat discs and internal surface relief products generally use plastic pressing. Plastic pressing is usually operated by two people at the same time. The whole process includes cutting mud, putting mud, air flushing, tearing, connecting blank, wiping, trimming, and putting on the shelf. . And regularly drain the mold.
The handle of the mug and most special-shaped products require a grouting process. Grouting is more cumbersome and more expensive than rolling and plastic pressing. But at the same time, the value of special-shaped products is usually higher. Grouting includes the steps of grouting, pouring, turning over the mold, ejecting the mold, and finishing the mold.
