However, the colored glaze on the ceramic surface may become a health killer. Lead, mercury, radium, cadmium, etc. in colored glaze are all harmful elements to the body. The radioactive element radium kills white blood cells. Cadmium, lead and mercury are all heavy metals.

When unqualified ceramic products are used, these harmful substances will dissolve and enter the human body with food. Over time, it will cause chronic poisoning. At the same time, attention should also be paid to the clay used to make ceramics. Inferior clay contains more microorganisms and harmful substances.

The colored glazed ceramics that meet the standards are basically harmless to the human body, but the clear-looking bone china cups may bury hidden dangers for health.
