When people drink water or other drinks from glasses, they don't have to worry about chemicals being drunk into their stomachs. Moreover, the glass surface is smooth and easy to clean, so it is healthy and safe for people to drink water from the glass.
Precautions in the use of glass: glass is afraid of thermal expansion and cold contraction. Don't put hot water into a glass with low temperature immediately to prevent it from bursting.
