    IntroductionPropertiesUsesHistoryFormationResourcesMiningProcessingHumans used lead as long ago as 5000 BC; it was shaped for all sorts of uses ranging from water pipes to coins. It continues to be used to this day in a wide range of applications. Have you ever seen the beautiful stained-glass windows of churches, where the glass is held together by lead? Did you know that car engines rely on a lead-acid battery to start up? Or perhaps you are aware that when you watch TV or use a computer, it is lead that screens you from harmful radiation. Lead is certainly an important metal.
