Abstract

The invention discloses a high-hardness Jun porcelain copper red glaze, which is prepared from the following raw materials in parts by weight: 22-30 parts of feldspar, 6-10 parts of white feldspar, 6-10 parts of kaolin, and 8 parts of wollastonite ‑12 parts, talc 8‑12 parts, quartz 20‑24 parts, calcite 10‑14 parts, copper oxide 0.9‑1.1 parts, zinc oxide 1‑3 parts, silicon carbide 1.1‑1.3 parts. The preparation method of the high-hardness Jun porcelain copper red glaze includes the following steps: (1) crush the above-mentioned raw materials and put them into a ball mill for ball milling, add water to make the mass concentration of the glaze reach 54-55%, and wet mill for 14-55%. After 16 hours, the wet-grinded slurry is passed through a 200‑300 mesh sieve to obtain a glaze slurry; (2) Glaze is glazed by dipping, and the thickness of the glaze is 1mm~1.3mm; (3) Firing, the firing temperature is 1280‑1320°C .

Description

technical field [0001] The invention relates to the technical field of Jun porcelain manufacturing, in particular to a high-hardness Jun porcelain copper red glaze and a preparation method thereof. Background technique [0002] Jun Porcelain is a unique national treasure porcelain in Shenhou Town, Yuzhou City, Xuchang City, Henan Province. With its simple shape, exquisite craftsmanship, complex glaze matching, and the magical kiln transformation of "one color in the kiln, thousands of colors in the kiln", the scenery of lakes and mountains, clouds and clouds Fog, human, animal, flower, bird, insect, fish, etc. are known as the first of the "Five Famous Porcelains" in China. [0003] Red is the most expensive ceramic decoration, and there are many types of red glaze, among which copper red glaze has the longest history. Copper red glaze is a precious product developed after celadon glaze. It matured in Henan Jun kiln in the Northern Song Dynasty, and was inherited and develo...
