Water cups are the most commonly used on weekdays, but there are many kinds of cups. As far as cup materials are concerned, there are common cups, enamel cups, ceramic cups, plastic cups, stainless steel cups, paper cups, thermos cups, health cups and so on.

The first choice for drinking cups is glasses. Don't think that glass is just transparent and beautiful. Among all the cups made of materials, the glass is the healthiest.

Professor Li Fuxing, Chairman of the Health Water Professional Committee of Chinese Medical Association, listed the characteristics of glass water cups: the cups do not contain organic chemicals in the firing process, so when people drink water or other drinks from the cups, they don't have to worry about the 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, so it is the healthiest and safest for people to drink water from 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.

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 cleaned properly, bacteria can easily breed. Therefore, experts remind that when purchasing plastic cups, you must choose cups made of food-grade plastics that meet national standards.
