For adults, they can just buy whatever they like and use it, especially when they see a cup they like in the supermarket, or a container they like in the store, they can buy it and use it to hold rice. However, considering the special physical constitutions of children, and the fact that parents want to give their children the best, baby drinking cups are carefully selected. What material should be used for baby drinking cups has become a concern for many people. Which material is best for drinking water cups? Glass cups, enamel cups, ceramic cups, plastic cups, stainless steel cups, iron cups, aluminum cups, wooden cups, paper cups, when we go to the mall to buy water cups, all kinds of cups will come into our sight, especially those with bright colors and unique shapes, which make people like them even more. We will be dazzled after choosing so many. The first choice for drinking water should be a glass. Don’t think that glass cups are just transparent and beautiful. Among all cups made of different materials, glass cups are the healthiest. Characteristics of glass cups: Glass cups do not contain organic chemicals during the firing process. When people use glass cups to drink water or other beverages, they don’t have to worry about the chemicals being drunk into their stomachs. The glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the wall of the cup. Therefore, it is healthiest and safest for people to drink water from glass cups. In addition, experts also advocate the use of enamel cups, because enamel cups are made after high-temperature enameling at thousands of degrees, do not contain harmful substances such as lead, and can be used with confidence. However, experts have raised questions about cups made of other materials. Colorful ceramic cups are very pleasing to the eye, but in fact there are huge hidden dangers in those bright pigments, especially when the inner wall is coated with glaze. When the cup is filled with boiling water or highly acidic or alkaline beverages, the toxic heavy metal elements such as lead in these pigments will easily dissolve in the liquid. When people drink the liquid containing chemicals, it will cause harm to the human body. Plasticizers are often added to plastics, which contain some toxic chemicals. When you use a plastic cup to hold hot or boiling water, the toxic chemicals are easily diluted into the water. In addition, the internal microstructure of the plastic has many pores, which hide dirt. If it is not cleaned properly, bacteria will easily breed. Therefore, experts remind that when purchasing plastic cups, you must choose water cups made of food-grade plastic that meets national standards. |
