These ceramic tableware heavy metal exceeds bid!

Due to the complexity of glair and glaze color process, high costs, with illegal businessmen use the glaze on technology, and combined with low temperature reinforcement, fluxing agent and the fluxing agent contains a lot of lead oxide, would also lead to human poisoning. Human body takes in too much heavy metal, can appear poisoning phenomenon, and even death. There exists heavy metals mainly stainless steel tableware and ceramic materials. Because in order to prevent rust, stainless steel tableware will contain a certain amount of chromium, nickel, if tableware surface coating damage, chromium, nickel can precipitate, endanger human body health. The engraved on the ceramic tableware glaze color decorative pattern, contain a certain amount of lead. So what is a harm to human body of heavy metals? 1 damage to the blood circulation system after heavy metal poisoning, blood viscosity, low oxygen content, the symptom such as severe words will lead to a fullness, shock; 2 damage to the nervous system will hold heavy metal poisoning and interfere with the function of the nervous system. Come, we should be how to distinguish? 1, when the choose and buy, choose regular business and market, not on the side of the road, vendors and other informal place to buy. Identify ceramic tableware production producers, because the country has a regulation, ceramic tableware before leaving the factory to ensure that in 4% acetic acid solution after soaking, tableware to the dissolution of lead content in less than 7 mg/l, cadmium dissolution amount to less than 0. 5 mg/l, used to match. Regular producers tend to meet this requirement, without formal manufacturers there is no guarantee that meet this standard. 2, observe the colour of ceramic tableware, glaze even, appearance design and detailed, not rough, tableware fingered the surface is smooth, especially the inner part, good quality tableware is no uneven granules. 3, smell the ceramic tableware, smell of tableware harmful element content is high, not to buy. 4, don't buy because the pursuit of beautiful, novel, plenty of bright color, design of ceramic tableware, the tableware for more good-looking, is usually added some heavy metal additives in glazes, heavy metals are harmful to human body. So the more bright-coloured ceramic tableware, the more its heavy metal content, are more likely to exceed bid. 5, the suggestion is that the choice of glair, under the glaze color process of ceramic tableware, these two kinds of process in the manufacturing process more stringent requirements, and the pigment content of heavy metals in less. 6, ceramic tableware in boiling water for 5 minutes before you use, or use vinegar bubble 2 - 3 minutes, can let the tableware of toxic elements dissolution.
