AnswermaybeNo. All crystal does not contain lead. There was a time that the increased lead content was considered a good thing, making it heavier and giving it a more substantial "heft" when you picked it up. It was a selling point and commanded a higher price. Now, however, it has been determined that the lead can leach into the liquid inside, like in a wine decanter that is filled with wine and sits quite a while. And, of course, lead in the blood stream causes many horrific symptoms and contact should be eliminated or at least reduced as much as possible. There are crystal products that have no lead, though.

The lead in the crystal gives it a brighter shine. The lead also allows the glass to be cut in intricate and unusual ways.

Ordinary glass can be mass produced and molded to form the design- not crafted.
