The glaze coating of some ceramic products may contain toxic substances such as lead. If the glaze coating falls off, these toxic substances are easily ingested into the human body. The glaze coating of some ceramic products may contain heavy metals such as barium and chromium, and excessive contact will be harmful. Long-term intake or inhalation of harmful substances may damage the human nervous system, hematopoietic system, liver and kidney, and even cause diseases such as cancer.
Therefore, once the ceramic glaze coating is found to fall off, it should be stopped immediately to avoid further contact. At the same time, ceramic products should be placed in a ventilated place to prevent toxic substances left in glaze coating from entering the human body. If you need to use ceramic products, you should choose products that have passed quality inspection to avoid buying low-quality or fake and shoddy products.
