What are the eight processes of ceramic firing?

The eight processes of ceramic firing are:

1. Mud training: Take porcelain stone, break it into pieces the size of an egg with a hammer, then hammer it into powder with a water hammer, then wash it, remove impurities, and make it into brick mud after precipitation.

2. Blanking: drop the clay ball in the center of the turntable of the pulley car, and draw the basic shape of the blank according to the flexion and extension of the manual.

3. Blank printing: according to the internal arc of the blank, the shape of the stamp is formed by rotary cutting. Cover the semi-dry blank on the mold, beat the outer wall of the blank evenly, and then demould.

4. Blanking: put the blank on the bucket of the pulley car, and cut it with a knife while rotating the wheel until the blank thickness is appropriate.

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

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

7. Glaze: Glaze or shake glaze is generally used for ordinary round instruments, and blow glaze is used for knives or large round instruments.

8. Kiln firing: First, put the ceramic products into the sagger. Kiln burning time is about one day and night, and the temperature is about 1300 degrees. It is also necessary to measure the fire temperature to determine the ceasefire time.
