The ceramic cup is made of clay and has no toxic and side effects. The so-called poison on the ceramic cup mainly refers to the dissolution of lead and cadmium. Generally speaking, in order to make the surface of ceramic cups look good, color patterns are usually decorated on the surface, and lead and cadmium are mainly introduced by these colors. The ceramic cups of regular manufacturers have been strictly tested. The dissolution of lead and cadmium meets the national mandatory standards, so they are safe and reliable.
Of course, some ceramic cups produced by small factories use inferior raw materials in order to be cheap, which will lead to excessive dissolution of lead and cadmium, and long-term use will affect human health. Therefore, do not choose ceramic cups with very red and blue patterns, which are prone to excessive dissolution of lead and cadmium. A single color glaze cup is generally safe and non-toxic, and can be used at ease.
Ceramic cups can be divided into overglaze color and underglaze color. Many overglaze colors are printed with flower paper. When you touch them, you will feel uneven. If the patterns on such vessels are not well done, they are easy to fall off, which will do some harm to the human body. Try to choose underglaze color.
