What kind of glass water cup is good for drinking water?

Glass bottle is the healthiest. Professor Li Fuxing, Director of Health Water Professional Committee of China Medical Promotion Association, has counted the characteristics of glass bottle: glass does not contain organic chemicals in the process of firing. When people drink water or other drinks with glass bottle, they do not have to worry about the chemical substances being drunk into their stomachs, and the glass bottle surface is smooth and easy to clean. Bacteria and dirt are not easy to breed on the glass wall. People drink water from glass is the healthiest and safest. In addition, experts also advocate the use of enameled cups, because enameled cups are made after thousands of degrees of high temperature enameling, without harmful substances such as lead, can be used at ease.

But experts have questioned cups made of other materials. Colorful ceramic cups are very pleasant, but in fact there are huge hidden dangers in those bright pigments, especially glazed inner walls. When the cups are filled with boiling water or drinks with high acidity and alkalinity, toxic heavy metal elements such as lead in these pigments are easily dissolved in liquids. People drink liquid with chemical substances, which will cause harm to human body. Plasticizers are often added to plastics, which contain some toxic chemicals. When hot water or boiling water is filled in plastic cups, toxic chemicals are easily diluted into water, and the internal micro-structure of plastics has many holes, which hide dirt, and bacteria can easily breed if it is not cleaned properly. Therefore, experts remind us that when choosing plastic cups, we must choose water cups made of edible grade plastics that meet the national standards.
