Lead smelting - Wikipedia
The earliest known cast lead beads were found in the Çatal Höyük site in Anatolia (Turkey), and dated from about 6500 BC, but the metal may have been known earlier. Ancient smelting was done using loads of lead ore and charcoal in outdoor hearths and furnaces. Although lead is a common metal, its discovery had relatively little impact in the ancient world. It is too soft to be used for weapons (except possibly as slingprojectiles) or for structural elements. However, bei…Lead - Essential Chemical Industry,currently used by the secondary lead industry.
