Ceramic cups actually hide huge hidden dangers in those bright pigments, especially the inner wall is coated with glaze. When the cups are filled with boiling water or drinks with high acid and alkalinity, the toxic heavy metal elements such as lead in these pigments are easily dissolved. In liquids, people drink liquids with chemical substances, which will cause harm to the body.
The glass is not only transparent and beautiful, but it is the healthiest among all materials. The glass does not contain organic chemicals during the firing process, and when people use it to drink water or other beverages, they don’t have to worry about the chemicals being drunk into the stomach. At the same time, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the wall of the cup.
To sum up, compared with the glass cup, the latter is better for drinking water, which is both healthy and safe. However, if you choose a ceramic cup, it is still better than a glass cup. Of course, the quality must pass the test.
