Embodiment 1
[0032] A decoration method for high-grade underglaze color ceramics, which is produced by three-firing method. Firstly, the green body is bisque-fired, then color-fired, and finally glaze-fired; The three-firing method of firing, high-temperature color firing and bottom-temperature glaze firing is used to make underglaze colored ceramics; the specific manufacturing process steps are as follows:
[0033] 1. Blank making: refining the raw materials for making underglaze color ceramics into mud blanks, and then making blanks of the required shape according to needs;
[0034] 2. High-temperature biscuit firing: place the formed biscuit in a biscuit sagger for firing; the bisque firing is to put the prepared biscuit in a sagger with a cover, and fasten the sagger cover so that The biscuit is in a closed state in the sagger; then the sagger with the biscuit is placed in the bisque firing furnace, and bisque firing is carried out at a temperature of 1250°C;
[0035] 3. Color paintin...
