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.

In addition, plastic cups are also very easy to breed bacteria and hide dirt, so pay attention to frequent cleaning.

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.
