preparation example Construction

[0032] Its preparation method comprises the following steps:

[0033] Step 1, preparing base slurry, peacock blue glaze slurry and transparent glaze slurry;

[0034] Step 2, use the base slurry obtained in step 1 to prepare a ceramic body. After the ceramic body is dried, apply the peacock blue glaze slurry prepared in step 1 on the ceramic body in a glazed manner, wherein the peacock blue glaze slurry The thickness is 0.8-1mm;

[0035] Step 3: Put the peacock blue glaze slurry into a kiln after drying, and fire it into a porcelain body under a reducing atmosphere at 1230-1280°C. The specific firing control is as follows:

[0036] Low temperature stage: the temperature in the kiln rises from normal temperature to 320-350°C, and the kiln firing time is 1-2h;

[0037] Decomposition and oxidation stage: the temperature in the kiln is raised to 820-850°C, and the kiln is fired for 3-4 hours;

[0038] High-temperature strong reduction stage: the temperature in the kiln is raised...
