1. In terms of porcelain quality, there are many kinds of porcelain in ceramic tableware, including bone porcelain, white porcelain, celadon and painted porcelain, but in terms of quality, tableware with high white porcelain and bone porcelain is better, because both white porcelain and bone porcelain have the characteristics of high transparency and light texture. If you choose from porcelain, ceramic tableware with high white porcelain is a good choice.

2. From the perspective of picture decoration, ceramic tableware can be divided into over-glaze color, in-glaze color, under-glaze color, colored glazed porcelain and some unglazed white porcelain, among which the under-glaze color is mainly traditional blue and white, and the color is monotonous. However, the in-glaze color is richer than the under-glaze color, and the product grade is higher, but the process requirements are strict and the cost is high. Therefore, from the perspective of decorative effect, ceramic tableware with color in glaze will be better.

3. Look at the quality of porcelain glaze. No matter what kind of ceramic glaze you choose, you should choose a ceramic glaze with low content or no heavy metal elements such as lead and cadmium, which can be judged by the quality inspection certificate of the merchant. Of course, if you still don't feel at ease, you can buy high white porcelain tableware directly, because it doesn't contain lead and is harmless to the human body.

4. Look at the craft of ceramic tableware. If you want to judge the craft level of ceramic tableware, you should not only judge whether the surface of ceramic tableware is smooth, deformed and black spots, but also whether tapping ceramic tableware can really make a crisp and pleasant sound. If possible, then the quality of such ceramic tableware is still good.
