For a home, cups are indispensable. So what materials are the cups made of?
1. Stainless Steel Cup
Stainless steel cups are alloy products. Improper use will release heavy metal substances contained in them, which is harmful to health. Therefore, in daily use, do not use stainless steel cups for acidic drinks, such as juice, coffee, carbonated drinks, etc. When cleaning stainless steel cups, do not use strong oxidizing soda, bleaching powder, etc. These substances are also prone to chemical reactions with stainless steel.
2. Ceramic Cup
Ceramic cups are bright, beautiful, and have a variety of shapes. They are the most popular type of cups on the market.
Ceramic cups are very safe and healthy cups. You don't have to worry about ingesting harmful metals after being used for a long time like metal cups, and you don't have to worry about the precipitation of harmful substances in hot water like plastic cups.
3. Plastic Cup
The additives and low-molecular-weight substances in the plastic cup are easily precipitated after being heated. Therefore, you should try to fill as little hot water and hot drinks as possible. Plastic cups should also not be stored in the refrigerator for a long time, as the low temperature will cause the plastic to degrade. In addition, plastic cups are also very easy to breed bacteria and hide dirt, so pay attention to frequent cleaning.
4. Glass Cup
At present, high borosilicate glass is generally used on the market, which is characterized by high temperature resistance and small meaning of 100°. It can withstand instantaneous temperature changes of about 0-160 without cracking. Moreover, the transparent material is easy to clean, and it is not easy to hide dirt.
5. Enamel Cup
Enamel is resistant to high temperature and corrosion, and the metal substances contained in it are relatively stable, but may be dissolved in an acidic environment, so it is best not to use enamel cups to hold acidic drinks for a long time. When purchasing, carefully observe whether the inner wall and rim of the enamel cup are damaged, and touch the inner wall and rim with your hands. Do not buy if damaged.
