If you like Tupperware cups, you can choose cups specially used for boiling water. Their service temperature is generally -20 to 1 10, which is different from Liang Yu Cup.
As for the choice of drinking cup, the first choice should be glass. This kind of glass contains no organic chemicals in the firing process. When people drink water or other drinks from glasses, they don't have to worry about chemicals being drunk into their stomachs. Moreover, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the glass wall. Therefore, it is the healthiest and safest for people to drink the water in the glass. In addition, experts also advocate the use of enamel cups, because enamel cups are made of thousands of degrees of high-temperature enamel and do not contain harmful substances such as lead, so they can be used with confidence.
Colorful ceramic cups are pleasing to the eye, but those bright pigments actually hide huge 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 because they 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. Therefore, experts remind that when purchasing plastic cups, you must choose cups made of food-grade plastics that meet national standards.
