Painted pottery refers to the polished orange-red pottery blank, depicted with natural mineral pigments, ochre and manganese oxide as color elements, and then fired in a kiln. On the orange-red carcass presents a beautiful pattern of ochre red, black, white, and various colors, forming a pottery with a high degree of unity between the pattern and the shape of the utensil, and achieving the decorative and beautifying effect.
Painted pottery is exquisitely made, mainly clay pottery, with a delicate texture, so it is not only a practical vessel, but also has high artistic value. Since the color is painted before firing, after roasting with the pottery, the color and the pottery tire are closely combined and are not easy to fall off. The form of painting can be generally divided into two categories: patterns and pictures.
Second, the surface of the ceramic blank must reach a certain finish, and the pigment can penetrate into the ceramic tire. This requires careful screening and washing of clay, and repeated polishing of the table after the billet is formed. Most of the painted pottery in archaeological discoveries is clay pottery, and even the sand pottery such as the Xindian culture has a relatively delicate surface. The main body of Dadiwan cultural pottery is fine sand pottery, but the surface of the ware is coated with a smooth argillaceous layer;
