Manufacturing method of transparent pea green-color thin glaze of Ru porcelain
The invention discloses a manufacturing method of transparent pea green-color thin glaze of Ru porcelain. The manufacturing method comprises the following steps of respectively taking 5-10% of melilith, 10-20% of calcite, 45-65% of white feldspar, 15-22% of black feldspar, 5-10% of quartz and 1-3% of plant ash as glaze materials, crushing the glaze materials to powder of 40 meshes, carrying out grinding, removing floating iron in the glaze slurry by a magnet rod so that glaze is obtained, taking kaolin as a blank material, adding 45-50wt% of water and 0.3-0.5wt% of an alkaline water aqua into the blank material, carrying out wet grinding for 8-13h, preparing a blank from the slurry, sintering the blank to a temperature of 800-900 DEG C, carrying out natural cooling to obtain a biscuit, carrying out glazing on the biscuit, finishing the bottom, the surface glaze layer and a nonuniform part, putting the finished biscuit into a kiln, carrying out gradual heating to a temperature of 1040 DEG C in an oxidation atmosphere, carrying out slow heating to a temperature of 1250 DEG C in a reduction atmosphere, carrying out thermal insulation for 10min, stopping heating and carrying out cooling.
