As the name implies, ceramic cup is made of ceramic cup, its quality of material is harmless to human body, but also can play the role of health care, do you know how ceramic cup production process is?
The so-called "ceramic" is made of clay into a shape, by clay or other inorganic non-metallic materials, through molding, sintering and other technology processing, used for decoration and protection of building metope and the ground of the plate or block ceramic products. It is dried and heated to such a degree that it hardens and no longer dissolves in water.
1, mud: from the mining area to take porcelain stone, by water duichuang, panning, remove impurities, precipitated into brick-like mud. Then mix the mud with water again, remove the slag quality, rub with the hand, or trample with the foot, squeeze the air in the mud out, and make the water in the mud even.
2. Casting: throw the mud into the center of the wheel of the pulley, and make the rough shape of the body with the method of bending and stretching.
3. Billet printing: the shape of the impression is rotated according to the arc in the body of the billet, and the semi-dry billet is covered on the mold, and the outer wall of the billet is evenly patted, and then demudged.
4, the blank: the blank is placed on the bucket of the pulley car, turn the wheel, with the knife to cut, in the body thickness is appropriate, the surface and the inside smooth, this is a technical process with high requirements.
5, drying blank: the processed blank is placed on the wooden frame to dry.
6, carving: with bamboo, bone or iron knives in the dry or semi-dry body carved patterns.
7. Glaze application: immerse the body in the glaze for a moment, and attach the glaze slurry to the surface of the body by using the water absorption of the body. The thickness of glaze layer is controlled by the water absorption of the body, the concentration of glaze paste and the impregnation time.
8, kiln: the time process is about a day and night, the temperature is about 1300℃. First build the kiln door, fire the kiln, the fuel is pine wood, the pile worker technical guidance, test the temperature, master the kiln temperature change, determine the cease-fire time.
9, color glaze: glaze the billet of the first 800℃ by low temperature burning, and then painting, and then spray a layer of thin glaze on the surface, and then by high temperature firing; Color sandwiched between two layers of glaze, is a veritable glaze porcelain.
