Drinking water has become a healthy habit in daily life. Using the wrong cup may "slow down" health. Because you choose the wrong cup to drink water, you may also bring some harmful substances into your body. At present, there are many kinds of cups on the market, including glass, ceramic, plastic and stainless steel. Which is the safest and healthiest?
1. Glass: the first choice for drinking glass is glass, especially for office or home users. Glass is not only transparent and good-looking, but among all materials, glass is the most healthy and safe. The glass is made of inorganic silicate. There are no organic chemicals in the firing process. When people drink water or other drinks with the glass, they don't have to worry about the chemicals being drunk into the stomach. The glass surface is smooth and delicate, easy to clean, and bacteria and dirt are not easy to stick to the glass wall, so it is safer for people to drink water with glass.
2. There are two types of ceramic cups:
A ：colorful: there are colorful patterns on the ceramic cup, which is pleasing in appearance. In fact, there are huge hidden dangers in the brightly colored pigments. There is a layer of glaze on the inner wall of the ceramic cup. When the glazed cup is filled with boiled water or drinks with high acid and alkali, heavy metal elements are easy to penetrate into the liquid. At this time, people drink liquid with chemicals, and the human body will be hurt.
B ：colorless glaze: colorless inner wall, safe material and high temperature resistance. The smooth surface of porcelain indicates that it is underglaze color or underglaze color, which is relatively safe; If the surface is uneven, it indicates that it is overglaze color. It is recommended not to buy it. Porcelain has a relatively heat preservation effect. Drinking water and tea is a good choice.
