According to related introductions, the ceramic tableware currently circulating in the market can be divided into overglaze, midglaze, underglaze, colored glazed porcelain and some colorless white porcelain tableware. As ceramic white porcelin dinnerware is decorated in different ways, the possible impact on health is also different. Among them, the lead and cadmium content in in-glaze, underglaze, and most glaze porcelains and white porcelain are low. Moreover, if the over-glaze chinaware ceramic use excessive amounts of lead and cadmium pigments during processing, or the temperature and ventilation conditions are insufficient during the baking process, it is very easy to cause excessive lead and cadmium dissolution. Another bone ash porcelain is white, its porcelain is transparent, the glazed surface is smooth and shiny, which is very popular among consumers. However, the production of this kind of porcelain is difficult, and most of them use high-temperature biscuit and low-temperature glaze firing processes.
