Problems solved by technology

Due to the large body of the bottle, if the blank is too thin, cracks are likely to occur during the firing process, and the strength of the bottle body is not enough
Therefore, the tire walls of the existing large-shaped Ru porcelain bottles are generally relatively thick, which affects the appreciation of Ru porcelain and the value of handicrafts.

Abstract

The invention relates to a technology for fabricating big vessel shaped Ru porcelain bottle, which comprises the following steps of: taking the following constituents in percentage by weight as blank materials: 15-20% of kaolin, 4-10% of camwood knot, 25-40% of hargil, 15-25% of chinastone, 4-10% of quartz and 15-20% of potassium feldspar; grinding the blank materials, adding water for wet grinding, and regulating water content of the slurry to 35-45%; making the slurry into blank bodies of bottle opening part, middle part and bottom part respectively, bonding by mud, wiping the blanks and burning into bisques; grinding glaze material, and adding water for wetly grinding into the slurry; wiping the bisques, and placing in the glaze material slurry for glaze immersion; and placing the bisques in a kiln, burning in oxidation atmosphere, increasing temperature of the kiln to 1050 degrees centigrade, burning in reducing atmosphere, insulating for 1h at 1050 degrees centigrade, increasing temperature to 1250 degrees centigrade, insulating for half an hour, stopping burning and cooling to finish fabrication of the big vessel shaped Ru porcelain bottle. In the technical scheme, the constituents are firmly combined, the fabrication method can improve strength of the Ru porcelain to prevent cracks, and the fabricated Ru porcelain has thin body, big vessel shape and high strength.

Description

technical field [0001] The invention relates to a manufacturing process of porcelain, in particular to a manufacturing process of a large utensil-shaped vase. Background technique [0002] Ru Porcelain is one of the five famous porcelains in my country. Its manufacturing process was lost for a time, but after hard research by technicians, production has now resumed. However, the current production of Ru porcelain is still based on antiques, and its production technology still has certain deficiencies. In the production process of Ru porcelain, the firing of large-shaped Ru porcelain vases, especially large-shaped lotus-leaf mouth bottles, is a technical problem. Due to the large bottle body, if the blank tire is too thin, cracks are likely to occur during the firing process, and the bottle body is not strong enough. Therefore, the tire walls of the existing large-shaped Ru porcelain bottles are generally thicker, which affects the ornamental value of Ru porcelain and the v...
