What are the materials of chopsticks

　　Now most of the chopsticks we use at home are bamboo and wooden chopsticks, and affordable bamboo chopsticks are common chopsticks in our days.

The chopsticks coated with raw lacquer are waterproof and bright, which will ensure the service life of chopsticks, reduce cracking and avoid hiding dirt.

　　Metal stainless steel chopsticks are loved by many people. They feel like holding them. The content of chromium in stainless steel chopsticks is generally more than 13%, and the content of nickel is also about 10%. The reason for rust is that there is a stable chromium rich oxide film (protective film) on its surface, which can avoid oxidation.

　　When using stainless steel chopsticks, try to avoid touching acid, alkali and salt, so that the surface oxide film will be damaged, and heavy metals such as chromium and nickel will enter the body. Generally, metal chopsticks are not suitable for the elderly and children, and when holding hot dishes, they conduct heat briefly, and be careful to burn your lips.

　　When buying stainless steel chopsticks, you can look at the label, which is generally 304 stainless steel.

　　Although ceramic chopsticks are healthy, who can guarantee that they will not fall to the ground when using chopsticks? Moreover, ceramic chopsticks are relatively heavy and inconvenient to use.

Generally, plastic chopsticks produced by regular manufacturers do little harm to health, but unqualified products simply produce substances harmful to human body when heated. Use plastic chopsticks to avoid high temperature.

　　Bone chopsticks have good texture, but they are simple and discolored, and are expensive. They are not suitable for daily use. What they like can be preserved as handicrafts.
