Which is healthier to drink water, a crystal cup or a glass?

Glass.

According to Yixiu Experience Network, drinking water from glass is healthier than crystal glass. Because the glass contains no organic chemicals, when people drink water or other drinks from the glass, they don't have to worry about chemicals being drunk into their stomachs, and the glass surface is smooth and easy to clean, so it is the healthiest and safest for people to drink water from the glass.

Glass refers to a cup made of glass, usually made of high borosilicate glass and fired at a high temperature of more than 600 degrees. It is a new type of environmental protection teacup, which is favored by people more and more.
