The Origin of Tangshan Ceramics

Tangshan is known as the "northern porcelain capital". Tangshan ceramics began in Yongle period of Ming Dynasty, with a history of more than 600 years. The main products are daily necessities, building porcelain, sanitary porcelain, industrial physical and chemical porcelain, high-tech porcelain, art exhibition porcelain and so on, with more than 500 varieties. The complete set of porcelain products includes: Chinese and western tableware, tea set, coffee set, wine set, stationery, smoking set, cup, plate, bowl, plate, remote control hanging plate, seat plate, porcelain plate painting, various vases, flower arrangement, etc. for display and appreciation; All kinds of porcelain carvings and sculptures; Practical ceramics and artistic ceramics such as large tile murals for architectural decoration. During the Yongle period of the Ming Dynasty, residents of Jiexiu, Shanxi and Zaozhuang, Shandong moved to Tangshan successively, bringing with them cylinder-making technology, and gathered in two areas in the northeast of the city to produce cylinder products using local raw materials and fuels. These two places were named Donggang Kiln and Xigang Kiln respectively. During the Guangxu period of the Qing Dynasty, coarse bowls with brown glaze were produced, and there were gray tire white porcelain with cosmetic soil and a small amount of antique porcelain. Later, under the influence of modern industry, Qixin Porcelain Factory, Desheng Porcelain Factory and Dongxiyao Porcelain Factory successively adopted mechanical equipment and new technology. In the 1920s, Qixin Porcelain Factory began to produce white porcelain without makeup, and all kinds of floor tiles and tiles were exported. From 65438 to 0935, sanitary porcelain was sold to Singapore, Malaysia and other places. Tangshan ceramic industry declined in the 1940s and recovered in the 1950s, forming a complete ceramic production system and entering the ranks of large ceramic production bases in China. 1956 began to export daily-use ceramics. 1On July 28th, 976, a major earthquake occurred in Tangshan, and the ceramic industry was completely destroyed. However, with the support of state and local governments, production quickly resumed. 1979 Tangshan porcelain began to enter the international market.

Tangshan porcelain belongs to K2O-Al2O3-SiO2 series, and the raw materials used are not only local bauxite, hard clay and soft clay (purple wood festival). ), timely and feldspar, as well as raw materials such as kaolin and porcelain stone produced in this province and other provinces, such as Tangshan ceramics Zhang Cun soil, Kuancheng soil, Xushui soil, Hengshui soil, Datong sand magnesia raw materials and Haicheng talc. Tangshan successfully developed twice-fired bone porcelain and white jade porcelain. After 1950s, we produced large-scale ceramic products, such as bathtubs and electroplating bath. In the 1980s, a new technology of microcomputer-controlled sintering in tunnel kiln was successfully developed by plastic extrusion ceramic molding.

It has a history of tens of thousands of years in China and is generally made of fusible clay. In some cases, clinker or sand can be added to clay to reduce shrinkage. The firing temperature of these products varies greatly, depending on the nature and quantity of impurities contained in the chemical composition of clay. If the porosity of bricks and tiles made of it is too high, the frost resistance of the green body is not good, and the mortar is not easy to cross, so the water absorption should generally be kept between 5 ~ 15%. The color of the green body after firing depends on the content of colored oxides in clay and the firing atmosphere. When fired in the oxidation flame, it is mainly yellow or red, and when fired in reducing flame, it is mainly cyan or black. The blue bricks in China's building materials are made of yellow or red clay containing fe2o 3. When the fire stops, they are calcined in reducing flame to reduce Fe2O3 to FeON and blue. Pottery can be divided into two types: ordinary pottery and exquisite pottery. Ordinary pottery refers to products with porous coloring bodies such as pottery pots, jars, altars, urns and refractory bricks. Tao Tang Yushun was born in Yucheng.
