Did you eat constellation ceramics? How about constellation ceramics?

Isn't the pattern of the ceramic bowl outside? Why do people say that colorful patterns contain harmful substances and will be eaten in the stomach?

From your question mark, I sorted out my answers, hoping to help you:

1, there are many kinds of ceramics. If it is white porcelain, then the outermost layer is transparent glaze. If it is an edible vessel, the main components are kaolin, feldspar, metal oxide and so on. All these substances come from the soil of the earth. If unscrupulous merchants add lead for brightness, the lead content will exceed the standard, and even white is problematic. If it is a regular manufacturer, there will be a very small amount of lead. The country has strict requirements on the content of lead (because eating too much lead will lead to poisoning, especially for children), and Europe and the United States have stricter specifications on the content of lead in ceramics. California 65 is a bill passed by the United States specifically for lead and cadmium content. As far as I know, China's pure white jade ceramics have passed the California 65 test. Personally, I think it is best not to choose products with flowers. You just need to see if European and American countries have imported glazed decals in China (yes, very few). . Ha ha laugh

In fact, almost all glass and ceramics have the same problem. It's not that the main component of glass is silicon dioxide. Qualified businesses have trace amounts of lead, depending on who has less.

So my personal opinion is that in this era, we need more brains and more basic knowledge. The safety factor of choosing high white and pure white ceramics is higher.
