Lead is obtained from its ores by a method used with many metals. First, the ore is roasted (heated in air). Roasting, also called smelting, converts the ore to a compound of lead and oxygen, lead oxide (PbO 2 ). Lead oxide is then heated with charcoal (pure carbon). The carbon takes oxygen away from the lead oxide.

The Difference Between Glass, Crystal, and Lead-Free Crystal

In Europe, they regulate crystal as anything containing 24% or more lead oxide. 24% is the standard for quality crystal and is the measure at which glass can be called "full lead crystal." Glasses using less lead oxide than 24% or using other oxide metals must be called "crystalline" or "crystal glass."
