Many people may not know much about the ceramic tableware they have purchased, and you are not sure of its quality, so you can use some small methods provided by our ceramic wholesale factory to test: ceramic tableware is afraid of acid, then use the newly purchased ceramic tableware. Before ceramic tableware, it can be soaked in vinegar to dissolve most of the lead; when using, do not use colored ceramic tableware to hold acidic food. In addition, when using, pay attention to the maintenance of ceramic tableware. Do not scrub ceramic tableware with wire, because it is easy to cause glaze scratches, and the scratches are easy to absorb dirt and cause lead, cadmium, etc. in the pattern to dissolve, which is not good for human health. Cracked ceramic tableware is also good, because the dirt in the cracks is not easy to clean, and it is easy for bacteria to multiply and cause diseases to enter from the mouth. The top ten brands of ceramic tableware are diverse in shape, delicate and smooth, bright in color and easy to clean. However, lead, mercury, radium, cadmium, etc. in the color glaze are all elements that are harmful to the body. Therefore, when purchasing ceramic tableware, you must choose carefully.
