What is the technological process of ceramic production?

1. Mud refining: take porcelain stone, make it into brick-shaped mud block by operation, then add water to the mud block and stir it to remove slag, and rub it with both hands to squeeze out the air in the mud block to make the water in the mud uniform.

2. Blanking: Drawing the rough shape of the blank is the first process of porcelain molding.

3. Blank printing: cover the blank on the mold, and then demould.

4. Blanking: Put the blank on the bucket of the pulley car, rotate the wheels and cut with a knife to make the blank have a proper thickness and smooth inside and outside.

5. Sun drying: put the processed blank on the wooden frame to dry.

6. Carving: Carve patterns on the dry blank with bamboo, bone or iron knife.

7. Glazing: ordinary round tools use glazing or swing glazing, and knives or large round tools use blowing glaze.

8. Kiln firing: First, put the ceramic products into the sagger. The box is a container for firing ceramic products, made of refractory materials, which is used to prevent direct contact between porcelain blanks and kiln fire and avoid pollution. Kiln burning time is about one day and night, and the temperature is about 1300 degrees. First, build the kiln door, and then ignite the kiln. The fuel is pine. Workers need to measure the temperature, master the temperature change of the kiln and decide the ceasefire time.
