Ceramic cup firing process the three most important process
1, glazing: In the glazing process, common round port with dip Glaze (enamel bowl immersed in the blank, when the rim is flush immediately with glaze made) or swing the glaze (glaze slurry injected into the inner billet shaking so down about evenly glazed, then quickly drained the excess glaze), carving and polishing (relative to 'Round "is concerned,' Round" means a method of forming through a circular throwing utensils, such as bowls, plates, dishes, etc. The molding process more complex containers, such as bottles, statues, pots, cans, etc., called "cut" on) Used for blowing or large circular glazed (method is to cast a bamboo yarn, dipped in glaze, mouth after blowing spray, so repeatedly, billet surface can have a glaze layer of uniform thickness).
2, kilns: sin kiln is time-consuming step, the time course of about a day and night, the temperature at about 1300 ℃. First puzzle kiln door, set fire to the kiln, the fuel is pine wood, the pile technical guidance, measuring look Huohou, master kiln temperature changes, decided ceasefire.
3, the glaze: overglaze as colorful, pastels, etc., is already depicted on glazed porcelain firing patterns, fill color, re-entry temperature roasting red furnace to a temperature of about 700 ℃ - 800 ℃. In addition, prior to that in the kiln body painting on prime tires, such as blue and white, underglaze red, etc., then known as underglaze red, which is characterized by high-temperature glaze color, never fade.
