Neither ceramics nor earthenware is harmful in itself, but it should be noted that the pigments used in ceramics and earthenware may contain heavy metals, which may have a potential impact on health. Specifically, pigments containing heavy metals such as lead may be used in the production of ceramics, and if the heavy metals in the pigments are dissolved, it may cause harm to the human body. Therefore, choosing ceramic products from regular manufacturers can reduce this risk. In contrast, earthenware products are relatively safer because they usually use natural pigments and contain less heavy metals.
To sum up, ceramics and earthenware are harmless to health, but attention should be paid to the safety of pigments during use, especially for high-risk groups such as children and pregnant women, and ceramics or earthenware products containing heavy metals should be avoided as far as possible.
