Abstract

The invention discloses a transmutation glaze ground coat which comprises the following components in percentage by mass: 70%-75% of frit, 5%-8% of kaolin, 4%-7% of zinc oxide, 1%-2% of barium carbonate and 10%-13% of ferric oxide. The invention further discloses a preparation method of the transmutation glaze ground coat and porcelain. According to the transmutation glaze ground coat, the preparation method thereof and the porcelain, a unique ground coat formula is adopted, good application of the transmutation glaze ground coat to the porcelain is achieved through mutual cooperation and combined action of all the components and the content of all the components, the porcelain rich in hue and variable in texture is obtained, and the glaze is resistant to abrasion, not prone to falling offand little in environmental pollution. The transmutation glaze ground coat is applicable to the technical field of ceramics.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a kiln-transformed underglaze, a preparation method thereof, and porcelain. Background technique [0002] Kiln-changing glaze is a general term for art glazes that produce kiln-changing effects during the firing process of ceramic glazes. The invention belongs to the technical field of ceramic glazes of inorganic non-metallic materials, and is used for the entire glaze surface and partial decoration of daily-use ceramics and art ceramics. Due to the poor viscosity of the existing kiln-changing glaze bottom glaze, the quality of the glazed surface of the kiln-changing glaze porcelain is affected, and the popularization of this kind of bottom glaze kiln-changing glaze on daily-use ceramics is limited. Therefore, it is very necessary to develop a kind of bottom glaze with wide applicability, make it adapt to the use of daily ceramics, enrich the decoration of ceramic glazes, and b...
