The difference between the white porcelain and bone China

What is the difference between the white porcelain and bone China? White porcelain is known as porcelain, basically everyone is seen, and bone China is not the same, bone China is to join the bone porcelain, porcelain is of good quality. White porcelain and bone China differ in that different raw materials formula, master bone porcelain is jingdezhen kaolin formula; Sintering temperature and sintering way also has difference, color difference. High white porcelain is pure white, bone China is milk white. Let's learn more about it! White porcelain is one of the traditional Chinese porcelain classification, with low iron content in porcelain billet, with pure transparent glaze, jingdezhen five generations used is the southern region has found early white porcelain of the origin of a product, its technology development has survived, and high white porcelain is jingdezhen selecting local superior raw materials such as kaolin, configuration, finishing with high temperature reduction burning them, firing temperature as high as 1350 degrees, the stability of higher, ceramic glaze color is pure and fine and smooth, pure and flawless, smooth and fair. Scientific name bone porcelain and bone China, bone China, is the animals' bone coal, clay, feldspar and quartz as the basic raw material, after high temperature, and low-temperature glaze burning fire burning in a porcelain. Speaking, as a raw material containing 25% bone porcelain can be called bone porcelain, recognized bone content higher than 40%, good quality bone China generally contain 51% superior cattle bone meal. The difference between white porcelain and bone China: first, different raw materials formula. Jingdezhen kaolin is famous for its history, color white, delicate a viscous, is the master of ceramic production raw material. Amount of kaolin is added to raw material, firing porcelain within the temperature range, which has high transparency, high strength, small deformation degree, glazed smooth level off, tonal and downy, etc. Combined with the iron content is higher in jingdezhen raw material, under the weak reducing atmosphere of jingdezhen traditional firing, has & other; White, green & throughout; Characteristics, it also became the leads the white porcelain in jingdezhen porcelain. Bone China is introduced in the porcelain making raw material of bone phosphorus or substances such as burning into ashes, join the ashes in porcelain firing process helps the melt, reduce the sintering temperature. The porcelain transparency is good, soft luster, soft, but porcelain brittle is bigger, thermal stability is poorer, so led to the bone China the shortcoming of easy cracking under high temperature. Second, sintering temperature and sintering method. Jingdezhen porcelain firing temperature is higher, can reach more than 1300 ℃, jingdezhen porcelain Jin Pintao gift co. , LTD. , production of a high white fine porcelain adopts & other; Secondary firing & throughout; , in the body before the glazing of low temperature and high temperature burning glaze firing, through secondary to improve the hardness and density of porcelain, and through the biscuit firing, oxidation, organic matter is crystallization water escape, carbonate and sulphate before glazing decomposition finished good to improve the product quality, product is not easy to deformation, glaze is more smooth and bright. And the bone porcelain firing temperature about 1200 ℃ & ndash; About 1250 ℃, sintering temperature which determines the density of porcelain body, the lower the firing temperature, porcelain texture is not dense, higher porosity and water absorption. This is bone China is in use for a period of time after the stain easily penetrate into the cause of the porcelain body cleaning not clean, in addition to the quality of a material, because of the low temperature burning, bone porcelain glaze easy to scratch, so bone porcelain sellers will tell you if there are any scratches, can use toothpaste polished lightly. And white porcelain because its sintering temperature is higher, the porcelain body dense hard, glaze color is more bright. 3, the color difference. High white porcelain is pure white, bone China is milk white. This is because the fire caused by temperature and the cause of the porcelain clay raw material. High white porcelain glaze color does not change color, bone China will color yellow in about 4 years. So we everyone heard of basic collection jingdezhen of ancient China, such as blue and white porcelain of yuan dynasty, Ming dynasty blue and white, but basically I haven't heard of collection of bone China. The above is the difference of bone porcelain and white porcelain, friends know about it?
