Ceramic products, as traditional materials for food contact, are ubiquitous in the daily lives of people worldwide. Items such as bowls, cups, soup pots, tea sets, knives, ladles, plates, and dishes are commonly made of ceramic materials. Ceramics are generally perceived by the public as safe, non-toxic, and healthy materials for daily life. They come in diverse shapes, with smooth and delicate surfaces, vibrant colors, and are easy to clean, making them highly favored by many. However, ceramic products still pose safety risks, primarily stemming from the glazing process. Glazes often contain sodium silicate and metal salts, and coloring pigments may also include metal salts, leading to the potential leaching of heavy metals. Therefore, countries worldwide have established clear regulatory requirements for ceramic products.
