In addition, experts believe that it is best to use enamel cups for drinking tea, because enamel cups are made of thousands of degrees of high-temperature enamel and do not contain some harmful substances, so they can be used with confidence.
Colorful ceramic cups are very pleasing to the eye, but in fact, those bright pigments have great hidden dangers, especially when the inner wall is glazed. When the cup is filled with boiled water or drinks with high pH, toxic heavy metal elements such as lead in these pigments are easily dissolved in the liquid, and people drinking the liquid containing chemical substances will do harm to the human body.
Plasticizers are often added to plastics, which contain some toxic chemicals. When hot water or boiled water is filled in plastic cups, toxic chemicals are easily diluted into water. There are many pores in the internal microstructure of plastic, which contain dirt. If it is not properly cleaned, it is easy to breed bacteria.
