Embodiment 1

[0015] The production method of Ru porcelain transparent bean green thin glaze, the production steps are as follows:

[0016] Step 1: select yellow feldspar, calcite, white feldspar, black feldspar, quartz, plant ash, respectively, as glaze raw materials, by weight 5% of yellow feldspar, 10% of calcite, 64% of white feldspar, 15% of black feldspar, 5% of quartz %, plant ash 1%, the selected raw materials are pulverized to 40 orders respectively, for subsequent use;

[0017] Step 2: Put the mixed glaze materials such as yellow feldspar, calcite, white feldspar, black feldspar and plant ash selected in step 1 into the ball mill, and then add water with a weight ratio of 50% of the mixed material for wet grinding. The wet grinding time is 18 hours , the glaze slurry after wet grinding is passed through a 150-mesh sieve, and the floating iron in the glaze slurry is removed with a magnet bar, and set aside;

[0018] Step 3: Select kaolin as the raw material of the billet, crus...

Abstract

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.

Description

technical field [0001] The invention relates to a manufacturing process of porcelain, in particular to a manufacturing method of Ru porcelain transparent bean green glaze. Background technique [0002] Ru porcelain is one of our five famous porcelains. The Ru kiln in the late Northern Song Dynasty was dedicated to firing imperial porcelain for the court, that is, "official Ru porcelain" for short. Its glaze color is characterized by "green as the sky, surface like jade, cicada wing pattern, morning stars, crab claws, pear skin, sesame flowers" and other special glaze colors. At present, Ru porcelain is mostly produced in the form of antique. And the usual Ru enamel is thicker. In the firing process of the conventional traditional technology, the temperature is also high, usually above 1250°C, the firing rate is relatively low, and the energy consumption is large. Contents of the invention [0003] The technical problem to be solved by the present invention is to provid...
