European standard for crystal cups
In the EU standard, the crystal glasses are divided into 3 types: lead free, medium lead and high lead. Lead oxide content in medium lead glass reaches 24%, and lead oxide content in high lead glass reaches 36%.
If crystal glass containers are manufactured according to European Union standards, no matter how much lead is contained in any product, there are strict international regulations, which should be safe for human body. However, due to the lack of standards in China, we can not rule out the arbitrariness of individual manufacturers, and the quality of products is difficult to guarantee.
