Can the Japanese porcelain bowls bought in Tik Tok be used for eating? Are they all used?

It is basically safe to eat with porcelain bowls, because porcelain bowls are treated at high temperature, so there will be no bacteria and viruses in them.

But if there are any patterns on the porcelain bowl, it may cause food poisoning, because those patterns will contain pigments and other things, and some bacteria will be attached to the surface, so it is best not to choose porcelain bowls with flowers.
