Why is it better to use white tableware?

Most household tableware is white. As long as there is a little dirt on white tableware, you can find it. However, the use of white household tableware is not only considered from this aspect, but also whether tableware has an impact on people's health. Household tableware is mostly ceramic, which is made of porcelain clay and kaolin by processing, glazing, melting and firing. Tableware is painted, the main component is white glaze: some are decals, hand-painted and printed dragons, all painted with colored materials. These pigments of different colors are mixed by pigments and cosolvents. Usually, pigments contain compounds of metal ions, and cosolvents are compounds containing lead. When the glaze of tableware is decorated and fired, due to the effect of additives, lead silicate Borui is generated, and bright colored glaze is formed, which is very beautiful. However, if these colored substances are eroded by acidic food, toxic elements such as lead and pot in the glaze will be chemically precipitated, polluting food and endangering human health. White enamel does not contain colored substances, and certainly does not contain these toxic elements. Therefore, the glass of tableware can only be painted outside, or painted with special materials. At present, some non-ceramic tableware also uses white, just to respect people's hygiene habits.
