The glass is stable in nature. Even if hot water is added, it is still a stable solid substance, and the chemical components in it will not precipitate and pollute the drinking water. Therefore, drinking water from a glass is theoretically harmless to the body. However, in order to beautify some glasses, more paints are used to draw the inner surface of the glass, or leaded glass is used in the production. If these glasses are used to drink water, it may cause harm to the body.
Generally, the quality of glasses bought in shopping malls can be guaranteed and will not cause harm to the body. However, if there is a lot of pigment in the glass, or if it is a low-quality lead-containing glass, after pouring some acidic beverages or hot water into the glass, some lead ions or other harmful chemicals may be precipitated, thereby polluting the drinking water. If these cups are used for a long time, it may cause harm to the body, such as chronic lead poisoning, allergic reactions, liver and kidney function damage, etc. Therefore, it is safer to choose a high-quality glass with no paint decoration on the inside.
In addition to drinking water from glass cups, people can also use disposable paper cups or ceramic cups to drink water, which generally do not produce harmful substances, but for safety reasons, it is also necessary to avoid using cups decorated with paint on the inside.
