The ceramic cup is made of clay, which itself has no toxic 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 the ceramic cup look good, the surface is usually decorated with colorful patterns, and lead and cadmium are mainly introduced by these colors. The ceramic cups of regular manufacturers have been strictly tested, and their lead and cadmium dissolution is in line with national mandatory standards, so they are safe and reliable.
Of course, there are also ceramic cups produced by some small factories, which use inferior raw materials for the sake of cheap prices, which will lead to the dissolution of lead and cadmium exceeding the standard, and long-term use will affect human health. Therefore, do not choose ceramic cups with very red and very blue patterns, which are prone to excessive lead and cadmium dissolution. A single color glaze cup is generally safe and non-toxic, and can be used with confidence.
Ceramic cups are divided into on-glaze color and under-glaze color. Many on-glaze colors are printed on floral paper. When you touch them, they will feel uneven. If the patterns on such utensils are not done well, It is easy to fall off and will cause certain harm to the human body. Try to use underglaze colors.
