Although ceramic tableware is beautiful and easy to use, there are still some things that deserve our attention when using ceramic tableware. Below we introduce the precautions for using ceramic tableware.
1. Although the color painting on the inner wall of ceramic tableware is bright, the color glaze contains heavy metal elements such as lead, mercury and cadmium. Among them, cadmium and lead are easy to cause liver or other internal organs poisoning, and mercury can cause liver and kidney cirrhosis. The more glazes on ceramics, the brighter the colors, and the more compounds such as lead and cadmium. When choosing ceramic tableware, don’t pay too much attention to patterns, especially don’t use dishes with painted inner walls. Newly bought tableware can be soaked in vinegar for 2 to 3 hours to dissolve the harmful substances in the color glaze. In addition, colored porcelain should never be heated in a microwave oven.
2. The underglaze color porcelain is the safest, and the pattern color is more blue and green, less red and yellow. Underglaze color is first to paint, then glaze, and then directly fired at high temperature. Since no low melting point substance is required, there is no need to add lead to the pigment, and the pigment is not easy to precipitate, which is the safest; underglaze color is glazed first. , and then paint, and then fired at high temperature, without lead, the pigment is difficult to precipitate, relatively safe. Where the underglaze has a pattern, the hand feel is as smooth as other places, and the gloss is very good, while the underglaze color is between the two, although the gloss is better, but the hand is not smooth.
