We all come into contact with ceramics in our daily life. Before the white body becomes porcelain, the necessary decoration is indispensable. According to the process and firing temperature, it is generally divided into three categories: on-glaze color, in-glaze color, and under-glaze color. Among them, the underglaze and the glaze are harmless to the human body. Because the temperature of the glaze is between 700-800 degrees, there is no deep melting into the ceramics. Under high temperature conditions, harmful substances will be released. ,pay attention.
In-glaze and under-glaze ceramic decorations are very rich. They can be painted with ceramic pigments on the semi-finished ceramic body, or they can be made into flower paper and attached to the body. If they are fired at about 1200 degrees, they belong to the glaze. The winning color, fired at high temperature, does not contain any harmful substances; if it is fired at about 1300 degrees, it belongs to the underglaze color, and the ceramic pigment is integrated with the embryo body, and does not contain any harmful substances. In use, if you touch the colored surface part of the ceramic by hand, the feeling of concave and convex is on-glaze color, if it is smooth to the touch, it is under-glaze and in-glaze color, which is easy to distinguish. The products produced by our factory are all in-glaze and under-glaze color products, and we are responsible for consumers.
