Thin porcelain is also called porcelain, which is used to describe it as thin to almost no lift. The production of thin-titanium is extremely demanding, and the most difficult and most important of the repairs. After the carcass is formed, the glaze in the device is dried, that is, the carcass of the unglazed glaze is scraped off, and only a layer of glaze is scraped off, and then the glaze is applied to the scraped surface. The blank is removed from the scorpion and repeated hundreds of times to repair the slab of two or three millimeters thick to the surface of the eggshell. After the burnt, the porcelain looked like it was taken out of the fetal bone, hence the name "out of the tires." During the Yongle period, the Jingdezhen kiln began to make thin-titan porcelain, and it had a high achievement during the Chenghua period. During the Longqing and Wanli years, even some high-grade folk kiln could burn high-thick porcelain, and there was a thin porcelain. Special names such as Liu Xia and preserved egg tarts. Production from the ingredients, casting, billet (repair), glazing to painting, firing, through more than forty procedures, all by hand, three times burned. In particular, the billet and art processing are the finest. The rough billet must be repaired repeatedly, repaired, refined, etc., and the blanks of two or three millimeters thick can be repaired to about 0.5 mm. The thickness of the carcass is mostly within 1 mm. It is called: it is thin like a flap, bright like glass, and light as a cloud. It is light, beautiful, exquisite in workmanship and good in light transmission. It is one of the traditional art porcelains in Jingdezhen, China. On the thin tire, there is a blue pattern (see blue and white porcelain), called blue and white thin porcelain; depicting a pastel pattern (see pastel porcelain), called pastel porcelain. During the Yongle period of the Ming Dynasty (1403–1424), Jingdezhen produced thin-tire porcelain, which has achieved high success in the years of Chenghua. The “Ovum Cup†produced in the Wanli Period (1573–1620) (thin eggshell cup) ), Liu Xia and other fine products, officially produced in the Qing Dynasty. In addition to Jingdezhen, Hunan Fuling, Guangdong Fengxi, Hebei Tangshan, Jiangsu Jiangyin and other places can now produce thin porcelain. After the founding of the People's Republic of China, the thin-tire porcelain process was inherited and developed. The thinness, transparency and whiteness of many products reached or exceeded the highest level in history. In addition to Jingdezhen, Hunan Fuling, Guangdong Fengxi, Hebei Tangshan, Jiangsu Jiangyin and other places can now produce thin porcelain. The varieties of thin porcelain include various tableware, stationery, tea sets, wine sets and craft table lamps. In 1986, there were hundreds of varieties, with a production capacity of more than 200,000 pieces. The styling specifications were developed to produce large-sized products such as bowls with a diameter of 500 mm and vases with a height of 500 mm. The thin porcelain has a thin body and low strength, and is easily broken and deformed during the manufacturing process. When manufacturing, you must have highly skilled operation skills and implement strict technical procedures. In the case of compounding, in order to prevent deformation of the thin tire product during firing, and to improve the whiteness and transparency of the glaze of the product, it is necessary to increase the content of alumina (Al2O3) in the billet and magnesium oxide (MgO) in the glaze. When roughing, it is necessary to carry out the roughing and finishing operation to make the thick blank into a blank of less than 1 mm in thickness. Before glazing, the billet is burned at a temperature of 750-800 °C. When glazing, the inner glaze is enamel glaze, the outer glaze is spray glazed, and the glaze layer is about 0.1 mm thick. The special cushion is used for the decoration, so that the fine blank is smoothly loaded into the crucible. The firing temperature is 1280 - 1320 ° C.
