Ceramic Tableware: Beware Of Lead Poisoning

Ceramic tableware does not rust, decay, and absorb water. Its surface is hard and smooth, and it is easy to wash. It has incomparable advantages over other tableware. However, ceramics contain lead. The relevant spot checks of the national quality supervision department showed that the excessive dissolution of lead has become a common problem of ceramic tableware. When people use this kind of tableware to hold fruits, vegetables, milk and other foods containing organic acids, the lead in the tableware will dissolve out and enter into human intestines, stomach, liver, kidney and other important organs and tissues along with the food. Over time, when the accumulation reaches a certain level, lead poisoning will be caused.

The excessive lead dissolution of ceramic tableware mainly comes from decorative materials. Experts remind consumers that when choosing ceramic tableware, they should choose tableware with small decorative area or safe underglaze color or underglaze color, and do not choose tableware with very bright colors and colored decorations on the inner wall. The decorative pattern of underglaze color is under the glaze, and the glaze covered on it is like a "safety film"; The in glaze color adopts the in glaze color paper to be quickly fired at a high temperature of about 1300 ℃, and it is relatively safe without using strong cooling solvent raw materials such as lead and cadmium. Overglaze colored porcelain is easy to identify by visual inspection and hand touch. The picture is not as bright as the glaze, the hand feeling is not smooth, and the edge of the picture has a convex feeling. In addition, consumers should not try to buy ceramic products cheaply at the stall, and try to choose lead-free glazed green tableware that is 3-4 times more expensive than ordinary ceramic tableware.
