1. Lead-free ingredients: The underglaze color does not contain lead in the production process, so it will not release harmful substances. In contrast, the bowl 304 is made of stainless steel, which contains a small amount of lead.
2. High-temperature firing: The underglaze color needs high-temperature firing in the production process, and the temperature can reach 1000 degrees Celsius or above. This high-temperature firing can effectively kill bacteria and viruses, promote the combination of underglaze color and bowl body more firmly, and reduce dissolution and shedding. In contrast, although the 304 bowl is resistant to high temperature, there is a risk of dissolution or falling off in daily use.
