You are here: Lead and crystal glass
Lead glass is 54 to 65 percent sand, 18 to 38 percent lead oxide, 13 to 15 percent alkali oxide and the rest consists of further oxides. Glasses which contain less than 18 percent lead oxide are also called crystal glass.* Crystal glass has a high level of light refraction and is perfect for decorative engraving. It has a far higher density than soda-lime glass. In our everyday lives, we use lead glass to make drinking glasses, vases, bowls, ashtrays or decorative ornaments.
* Some crystal glass doesn't contain any lead oxide. Crystal glass containing lead oxide is subject to a mandatory labelling requirement.
