What is the material of Korean tableware?

Spoons and chopsticks are basically stainless steel. But now there are some good plastic products that can't be ironed. Of course, if it is fried, chopsticks are particularly long and wooden. Other tableware, bowls, plates and the like are mostly porcelain. And plastic and stainless steel. Most Korean families use porcelain. Although expensive, it is good for your health. Because Koreans pay great attention to health. Most of the cups in restaurants are made of stainless steel and plastic. If it is used at home, it is still porcelain. This is what I saw in my life in Korea. I hope it helps you.
