Ceramic tableware is versatile, delicate, smooth, bright and easy to clean. It is the first choice for most households to buy tableware. However, the colored glaze on the ceramic surface may become a healthy killer. Lead, mercury, radium, cadmium, etc. in the glaze are all harmful elements.
Radioactive element radium can kill white blood cells. Cadmium, lead and mercury are heavy metals. Cadmium and lead can cause liver or other visceral poisoning. Mercury can cause liver and kidney hardening. When unqualified ceramic products are used, these harmful substances will dissolve. As the food enters the human body, it will cause chronic poisoning for a long time.
At the same time, ceramic clay should also be noted that inferior clay contains more microorganisms and harmful substances, even if it is not colored glaze will damage human health. Therefore, the specifications and quality of the products are particularly important. The glazed ceramics that meet the standard are basically harmless to the human body, while the seemingly clean and colorless ceramic tableware may pose a hidden danger for health.
