The lead content of some common crystal glassware in supermarkets or stalls may be as high as 24%. Such utensils can be used for ornamental display, but if they are used to hold food, especially acidic or alkaline food, lead will It will dissolve slowly and enter the human body through food, causing great harm to the human body.
Considering the factors of human safety and health, how to distinguish the difference between the two is particularly important!
Lead-free crystal glasses and lead-containing crystal glasses can be easily distinguished from the following 4 points:
①The lead-free crystal cup has better refraction than the traditional lead-containing crystal cup, and it perfectly shows the refraction performance of metallic glass;
②Look at heat resistance: Lead-free crystal glass is a glass with a high expansion coefficient, light and crisp, but poor in resistance to extreme cold and heat;
③Compared with lead-free crystal glass products, lead-containing crystal glass products are slightly thicker;
④Listen to the sound: Beyond the metal sound of lead-containing crystal glass, the sound of lead-free glass is more pleasant, and it is full of the reputation of "music" glass.
