Ceramic tableware is our common daily necessities. So, what should we pay attention to when choosing? Below, Qi Zhiyuan ceramics will tell us.
1. When buying ceramic tableware, you must choose a regular market. You must not buy cheap and inferior products without formal manufacturers. The state stipulates that when ceramic tableware is soaked in 4% acetic acid, the amount of lead dissolution shall not be greater than 7 mg / L, and the amount of cadmium dissolution shall not exceed 0.5 mg / L. The products of regular manufacturers can basically meet this requirement;
2, pay attention to the condition of the tableware when buying, touch the surface of the tableware with your hand to see if the inner wall is smooth;
3.Use your nose to smell if there is a strange smell;
4. Don't buy too bright ceramic tableware. In order to make the colors bright, manufacturers will add some heavy metal additives to the glaze, so the brighter the color of the tableware, the easier it is for heavy metals to exceed the standard;
5, should buy raw materials, process control more strict glaze color, underglaze color tableware.
