6 Ceramic Forming Methods
1. [Hand-pneading method] It is the most primitive and simple molding method to create the clay by hand, and pinch out some smaller utensils.
2. [Construction method of mud strips] Knead the soil into mud strips, build the mud strips into the wall from the bottom to the top of the container to the mouth of the container, then use the mud glue to synthesize the whole container, and finally smooth the wall plate of the container Cracks left during construction. This method appeared in the middle of the Neolithic Age.
3. [Mud piece enclosure method] First process the raw mud blocks into mud pieces, and then combine the mud pieces into the desired shape.
4. [Wheel forming method] A method of placing the mud on the roulette and using the centrifugal force generated by the rotation of the roulette to form. It is mainly used for the production of round shape, and the wheel system is divided into slow wheel and fast wheel.
5. [Impression method] A method of embedding mud into a special mold. Mainly used to make ceramic figurines, animal and utensil parts, ornaments, etc.
6. [Grouting method] A method of pouring mud into a mold such as gypsum, and using the capillary action of the gypsum model to adsorb the suspended slurry on the inner wall of the mold to form.
There are three types of molding processes currently used: rolling, plastic pressing, and grouting. Among them, rolling and plastic pressing belong to the impression method. These three types of molding methods are enough to control the shape changes of thousands of Taorun products. Rolling is used on products that are round, symmetrical, and embossed on the outer surface.
Square products, flat discs and inner surface relief products generally use plastic pressing. The plastic pressing is usually operated by 2 people at the same time. The whole process includes mud cutting, mud placing, air blowing, edge tearing, blank connection, wiping, trimming, and shelf. . And regularly drain the mold.
