Does this set of tableware contain no lead?

This set of tableware contains no lead. Because there is no colored glaze, there is no lead, and the quality of the mud is qualified. Ceramic dishes contain lead, which mainly refers to pigments. Ceramic tableware has become the first choice for most families to buy tableware because of its diverse shapes, exquisite smoothness, bright colors and easy cleaning. However, the colored glaze on the ceramic surface may become a health killer. Lead, mercury, radium, cadmium and other elements in colored glaze are harmful to health. When unqualified ceramic products are used, these harmful substances will dissolve out and enter the human body with food, which will cause chronic poisoning over time. At the same time, we should also pay attention to the clay for making ceramics. Inferior clay contains more microorganisms and harmful substances, even if it is not glazed, it will endanger human health. Therefore, the specifications and quality of products are particularly important. Standard colored glaze ceramics are basically harmless to human body, while colorless ceramic tableware that looks clean may pose a hidden danger to health. Don't pay too much attention to patterns in ceramic tableware, especially don't use tableware with painted inner walls. The newly bought tableware can be soaked in vinegar for 2~3 hours to dissolve the harmful substances in the glaze. In addition, painted porcelain should never be heated in the microwave oven.
