Pastel porcelain is also called soft colored porcelain. Pastel is a painting method that is painted on glaze (porcelain tire) and fired at low temperature. It is similar to pastel rice paper in that the picture color is light, and there are no or few heavy colors such as red and green.
Traditional color propaganda is hand-painted with mineral pigments. The specific process is still confidential, including the production process of rice paper. Although it was stolen by the Japanese, it was still classified as a confidential traditional craft.
