Chinese porcelain history

Generally believed that the so-called porcelain should have at least three conditions : porcelain china clay that can only be used for fetal Kaolin; child must be applied on the surface of glass glaze; porcelain firing temperature at least to 1200 ℃. Firing containers hard, it can knock issued touchstone sound, the finished product is very low water absorption. If such a request, the Shang Dynasty in China Etched white pottery and shell white pottery. Due to the quality of raw materials handling very sophisticated, fetal and glaze with a solid, easily peeled off, temperature control and heat skilled master is not enough, it can only be seen as the emergence of the original porcelain. Although not porcelain demand that is the invention of porcelain laid a good foundation. To the Eastern Han dynasty, had it that the invention of porcelain. This period of a mostly celadon porcelain, aggravation delicate and hard Component Application of the thick dense green glaze. This glaze is different from the early primitive celadon glazing thin, light green color stage. That is lime green glazed enamel, it is China's traditional Glaze, used for thousands of years, to create a unique style glaze. China's low-temperature glaze invention Although much later than the green-glazed ware, but not later than the Han Dynasty was introduced. This glaze lead to oxidation of flux, it is also known as the lead glaze. Lead in the glaze containing multiple color elements iron, copper, manganese, cobalt, so how much more colored glaze known. Only on the role of iron oxides, iron oxides are two issues : One is the oxidation of ferrous, was green glaze; is a three iron oxide, black glaze was brown or Red. Glaze with the reduction of iron as Yan Shaolian, we will be able to become ferrous oxide; As the flame Shaolian oxide, iron oxide can be turned into three. Tang of roughly Shaolian the Shiqianfeng NATURE porcelain, is the tendency of workers from the iron grasp changes in the manufacturing process. China White in the Southern WARE embryonic development in the Song Dynasty. In the Tang Dynasty, Neiqiu County, Hebei criminal kiln white, has developed into the green, two white porcelain is the mainstream. At that time, in addition to well-known criminal Kiln Kiln, there are Jingdezhen in Jiangxi and Sichuan Dayi kiln. 1958 Jingdezhen in Jiangxi Mai-ting Tang Dynasty unearthed in white bowls According to the research, white PORCELAIN more with calcium oxide, Sintering temperature had reached 1,200 ° C, the white porcelain has reached more than 70%, Clay High near modern standards. Song porcelain, the aggravation, glaze and technological aspects was promoted to a new level, Porcelain is the history of the development of an important phase, as well as firing in Room maturity period. In technology and techniques, as far as the election soil, crushing, panning, making mud, batching, fetal system, glazing, fire control, etc. There are clear division of labor. This production of the division, both Porcelain marks a new development, but also promoted the technical levels. In the Song Dynasty Ceramic Technology, in Yuxian County, Henan vessel found VARIABLE phenomenon. All contained in the glaze color elements iron, copper, which is fired in the kiln, because of the nature of flame and the temperature of different levels, as% of the glaze on with a variety of colors, colorful, dazzling breakthroughs in the past leagues, and the pure white colors. Ming porcelain burning technology, have made a big generation before progress. The outstanding performance of the refined White Glaze successfully produced. Because of this White Glaze contained lead oxide and silica composition is particularly high, and a modest increase in the amount of potassium hydroxide content, So Glaze translucent sprightly, white as milk. White Glaze improving the quality of single-colored glaze and glaze the development of the favorable conditions. Firing conditions Another achievement is the emergence of polychrome ware. OVERGLAZE a polychrome ware and two dccorating under glaze. Fetal bad on the first drawn veins colored logo again, after the kiln Shaolian polychrome ware called dccorating under glaze; After the glaze kiln firing on top of a porcelain painting, but also from burning stoves bake the porcelain called OVERGLAZE. Qing Dynasty porcelain, in the Ming Dynasty on the basis of further development. Ming Dynasty Chenghua, a struggle between Choi, Jiajing, a colorful 1590s. Choi called the Big Dipper, is the firing of porcelains add red, green, yellow, purple and other exotic ingredients, and then bake furnace burning opportunities. The so-called colorful, in fact may not be five colors, but the red color of colorful porcelain. This chemical process porcelain products, in the world of my earliest inventions. Far in China's Tang Dynasty porcelain, tea and silk in large numbers after the sea and the "Silk Road" marketing abroad, Since then successive have porcelain to sell abroad. 11 century, China made ceramic reached the Persian and later spread to the Arab countries, Turkey and Egypt. 1470 also spread to the Venice, Italy, Europe began production of porcelain.
