Does glass have lead in it?
Some glass has lead in it, specifically crystal glass. The lead acts as a flux in glass, allowing the grains of silica sand to be melted at a lower temperature. Glasses are generally denoted by their flux, so you get soda glass, flint glass, borosilicate glass, lead crystal etc. Lead also lends crystal the attribute of a high refractive index, making it a very clear glass and also soft. It can be easily cut with designs and polished. George Ravenscroft developed the first viable lead glass.
