Abstract

The invention relates to a method used for firing high temperature matte brownish red glazed porcelain in a reducing atmosphere. According to the method, in a green body and a glaze material, a common natural mineral material is mainly adopted at a certain ratio; raw materials such as glaze ash, dolomite, and white metal clay are added into the glaze material; one time firing is carried out at 1280 to 1320 DEG C in the reducing atmosphere so as to obtain the brownish red glazed porcelain. The method is capable of avoiding defects in the prior art that the glossiness of the obtained brownish red glazed porcelain is high, colour generation is nonuniform, and the primitive simplicity unique texture of Ming and Qing official ware brownish red glazed porcelain is impossible to achieve, and the method are capable of satisfying consumption requirements of returning to one's original nature of modern people. The raw materials are natural mineral raw materials, so that production cost is reduced greatly, it is beneficial for inheriting and promoting of excellent porcelain producing technology of our country, conditions are provided for improvement of the colour generation quality and stability of conventional porcelain products, and market prospect is promising.

Description

technical field [0001] The invention belongs to the technical field of traditional ceramic manufacturing, and in particular relates to a method for firing high-temperature matt purple-gold glazed porcelain in a reduction system, which is suitable for manufacturing various high-grade purple-gold glazed daily-use porcelains and display porcelains. Background technique [0002] Zijin glaze is one of the outstanding high-temperature color glazes of the ancient iron series. It developed to the Song Dynasty, and the Ziding produced by Ding Kiln (that is, Ding Kiln ceramic products with a sauce brown purple gold glaze layer on the surface) has become famous and widely recognized. They are well received and favored by the public, and the prices are high and hard to find. Among them, Su Shi, a writer of the Song Dynasty: "Lu Gong cuts tea to learn from Western Shu, Dingzhou flowers and porcelain cuts red jade" poems and Cao Zhao of Ming Dynasty "Ge Gu Yao Lun": "Purple fixes color Pu...
