Advanced Ceramic Ornaments crafts making:
Mud training: porcelain stone is taken from the mining area, first manually crushed with an iron hammer to an egg-sized block, and then beaten into powder by water hammer, washed, removed impurities, and precipitated to make brick-like mud. Then mix the mud with water, remove the residue, rub it with both hands, or step on it with your feet to squeeze out the air in the mud and make the moisture in the mud even.
Blank pulling: The mud ball is thrown in the center of the turntable of the reeling car, and the bending and stretching is carried out to pull out the rough appearance of the green body. Blank drawing is the first process of forming.
Blank: The shape of the impression is rotated according to the arc of the inner shape of the blank, and the blank that has been dried to semi-dry is covered on the mold, and the outer wall of the blank is evenly pressed, and then the mold is demolded.
Billet: Put the billet on the barrel of the reeling car, turn the disc, and use a knife to spin to make the thickness of the green body appropriate and the surface smooth, which is a process with high technical requirements. Billet, also known as "repair" or "billet", is the key link in determining the shape of the object, and makes the surface of the object smooth, coherent and regular.

It is not easy to ensure that the glaze layer of each part of the green body is uniform, the thickness is appropriate, and the different fluidity of various glazes is not an easy task.
Kiln: First of all, the ceramic products are loaded into the box, which is a container for the roasting of ceramic products, made of refractory materials, the function is to prevent the porcelain blank from direct contact with the kiln fire, to avoid pollution, especially for white porcelain firing is the most beneficial.

First build the kiln door, ignite the kiln, fuel is pine firewood, give technical guidance to the Tsubaki workers, measure the fire, grasp the temperature changes of the kiln, and decide the ceasefire time.
Painting: glaze colors such as five-color, pastel, etc., is to depict patterns and fill in on the glaze that has been fired into porcelain, and then bake it in a red furnace at a low temperature, the temperature is about 700-800 degrees. Before the kiln is burned, it is painted on the green body tem, such as blue and flower, glaze red, etc., which is called underglaze color, which is characterized by color under high temperature glaze and never fades.
