Not good. Because dinner plates have always been made of ceramics, the small butterfly pattern on the dinner plate is made of colored glaze, and the colored glaze on the ceramic surface is a health killer. Lead, mercury, radium, cadmium, etc. in colored glazes are all harmful elements to the body. So it is not good to have a small butterfly pattern on the dinner plate. Ceramics is the general term for pottery and porcelain, and it is also a kind of arts and crafts in my country. As far back as the Neolithic Age, my country has had rough and simple colored pottery and black pottery.
