Problems solved by technology

Although Jianbai porcelain has the artistic characteristics of the ancestors, due to the high price of raw materials and low quality rate of Jianbai porcelain, its popularization and promotion are restricted. It is decreasing year by year. The control of ceramic raw materials and the improvement of the firing process are necessary means to inherit and promote the traditional Dehua Jianbai porcelain. Huajian white porcelain has the closest artistic effect, while reducing the cost of Jianbai porcelain and increasing the firing rate. In the process of improvement, the selection of raw materials and the control of the firing process are technical problems that must be solved

Abstract

The invention belongs to the field of porcelain product and relates to Dehua Jianbai porcelain and a preparation technology thereof. The prepared Dehua Jianbai porcelain comprises a Jianbai porcelain body and Jianbai glaze; the Jianbai porcelain body is prepared from Dehua kaolin, low-temperature clay, a cold stone, Xianyou potassium feldspar, talc, quartz and bentonite at a ratio; and the Jianbai glaze is prepared from the cold stone, the quartz, limestone, aluminium silicate, the talc and the Dehua kaolin at a ratio. According to the Dehua Jianbai porcelain, the raw materials which are large in storage quantity and low in price are selected as the raw materials of the Jianbai porcelain body and the Jianbai glaze, and chemical components of the raw materials are strictly controlled, so that the transparency and the compactness are improved; through measurement, the whiteness is 70-78 degrees, the density is 2.5g / cm<3>, the water absorption rate is smaller than 0.1% and the transmittance is greater than 18% (1mm in thickness); and the porcelain has the artistic effect closest to that of traditional Dehua Jianbai porcelain.

Description

technical field [0001] The invention belongs to the field of ceramic products. Specifically, the invention relates to a Dehuajian white porcelain and a preparation process thereof. Background technique [0002] Dehuajian White Porcelain was called Baijian and Ivory White in ancient times. It sprouted in the Song and Yuan Dynasties, became popular in the Ming Dynasty, and was extended in the early Qing Dynasty. The porcelain color is white with flashing yellow, just like ivory. At the same time, due to the influence of different firing temperatures, atmospheres, heat preservation and other conditions, it produces pure white such as milk, white with flashing red and other porcelain colors. According to different porcelain glaze colors at home and abroad, , respectively endowed with elegant names such as lard white, creamy white, creamy white, pearl white, velvet white, and shrimp beard white. Jianbai porcelain is pure, delicate and dense, with beautiful and soft glaze color,...
