2. Glass tableware: "Crystal glass" has many hidden dangers
The glass meal has the characteristics of high hardness, stable chemical performance, smooth and easy-to-clean surface, and environmental protection. The glass tableware is clean and hygienic and does not contain toxic substances.
Crystal glass tableware is a threatening source of lead pollution. Since the lead oxide content in crystal products is as high as 20-30%, it will not cause lead poisoning if it is used to hold water. However, if it is used to hold wine, the wine will dissolve the lead in crystal glass products, and the longer it will dissolve The more the amount.
Similarly, when crystal glass containers are used to hold food, especially cola, honey, juice and acidic foods, lead ions are also easy to form soluble lead salts that are ingested by the human body with beverages or food, which seriously harms health. Therefore, crystal glass products are called "beautiful killers" by scientists.
