Problems solved by technology

Most of the current Ru porcelain is produced in the form of antiques, but there are still some shortcomings in the texture of Ru porcelain
Most of the current Ru porcelain is glass glaze, the surface glass texture is strong, and the aesthetics is not high
And the usual Ru enamel is thicker, generally reaching 1.0-1.2mm
During the firing process of the conventional production process, the kiln temperature is relatively high, usually above 1250°C, and the energy consumption is large

Embodiment 1

[0025] The production method of Ru porcelain matt thin glaze, the production steps are as follows:

[0026] Step 1. Select kaolin, yellow feldspar, calcite, albino feldspar, black feldspar and plant ash as glaze raw materials respectively, and the weight and number ratio of each raw material is: kaolin 4%, yellow feldspar 65%, calcite 18%, and albino feldspar 6% , black feldspar 6%, plant ash 1%; respectively pulverize the selected raw materials, pass through a 40-mesh sieve, and the sieve residue is not more than 1%, and set aside;

[0027] Step 2. Put the kaolin selected in step 1 into a calciner, and calcinate at a temperature of 920° C. for 6 hours. After calcining, turn off the heat and keep it warm for 35 minutes, then cool it down naturally for later use;

[0028] Step 3. Mix the yellow feldspar, calcite, white feldspar, black feldspar and plant ash selected in step 1 with the calcined kaolin in step 2, add the mixed material to a ball mill, and then add water with 45% ...

Embodiment 2

[0034] The production method of Ru porcelain matt thin glaze, the production steps are as follows:

[0035] Step 1. Select kaolin, yellow feldspar, calcite, albino feldspar, black feldspar and plant ash as glaze raw materials respectively, and the weight and number ratio of each raw material is: kaolin 10%, yellow feldspar 57%, calcite 19%, and albino feldspar 5% , black feldspar 7%, plant ash 2%; The selected raw materials are pulverized to 40 orders respectively, for subsequent use;

[0036] Step 2: Send the kaolin selected in step 1 into a calciner, and calcinate it at a temperature of 900° C. for 5 hours, turn off the heat after calcining and keep it warm for 30 minutes, then cool it down naturally for later use;

[0037]Step 3. Mix the yellow feldspar, calcite, albino, black feldspar and plant ash selected in step 1 with the calcined kaolin in step 2, add the mixed material to a ball mill, and then add water with 50% of the weight of the mixed material for wet grinding. ...

Embodiment 3

[0043] The production method of Ru porcelain matt thin glaze, the production steps are as follows:

[0044] Step 1. Select kaolin, yellow feldspar, calcite, albino feldspar, black feldspar and plant ash as glaze raw materials respectively, and the weight and number ratio of each raw material is: kaolin 6%, yellow feldspar 55%, calcite 22%, and albino feldspar 4% , black feldspar 10%, plant ash 3%; the selected raw materials are pulverized to 40 orders respectively, and set aside;

[0045] Step 2: Send the kaolin selected in step 1 into a calciner, and calcinate it at a temperature of 880° C. for 4 hours, turn off the heat after calcining and keep it warm for 25 minutes, then cool it down naturally, and set it aside;

[0046] Step 3. Mix the yellow feldspar, calcite, albino, black feldspar and plant ash selected in step 1 with the kaolin calcined in step 2, add the mixed material to a ball mill, and then add water with a weight of 55% of the mixed material for wet grinding. Th...

Abstract

The invention discloses a method for making an archaistic semimatte thin glaze for a Ru porcelain, which comprises the following steps: respectively taking 4-10% of kaoline, 55-65% of melilite, 18-22% of calcite, 4-6% of white feldspar, 6-10% of black feldspar and 1-3% of plant ash as raw materials for making the glaze; calcining the kaoline for 4-6 hours at a temperature of 880-920 DEG C for future use; mixing the melilite, the calcite, the white feldspar, the black feldspar and the plant ash with the calcined kaoline, adding water to the obtained mixture to carry out wet grinding on the obtained mixture, and removing natant iron to obtain a glaze material; selecting the kaoline as a blank material, adding the water and a water reducing agent to the blank material to carry out the wet grinding on the kaoline, and then, making slurry into a blank, and sintering the blank to obtain a biscuit; adding the water to the glaze material to adjust the concentration of the glaze material, immersing the biscuit in the glaze, and finishing the biscuit; putting the biscuit in a kiln, ventilating the kiln, increasing a temperature to 1050 DEG C, and then, reducing an inlet air amount, so that a fuel in the kiln is combusted incompletely in an anaerobic condition, and gradually increasing the temperature to 1135 DEG C; and preserving heat for 10 minutes, and then, decreasing the temperatureto 900 DEG C, stopping a fire, and cooling the obtained product, thereby completing the making.

Description

technical field [0001] The invention relates to a manufacturing process of porcelain, in particular to a manufacturing method of Ru porcelain antique matt thin glaze. Background technique [0002] Ru Porcelain is one of the five famous porcelains in my country. Its manufacturing process was lost for a time, but after hard research by technicians, production has now resumed. Most of the current Ru porcelains are produced in the form of antiques, but there are still some deficiencies in the texture and effect of Ru porcelains. Most of the current Ru porcelain is made of glass glaze, and the surface has a strong glass texture, but the aesthetics is not high. And the usual Ru enamel is thicker, generally reaching 1.0-1.2mm. During the firing process of the conventional production process, the temperature of the kiln is relatively high, usually above 1250°C, and the energy consumption is large. Contents of the invention [0003] The technical problem to be solved by the ...
