What Is Lead Smelting? - Wirtz Manufacturing

History of Lead Smelting. The process of creating lead can be traced back to 6500 B.C. Lead was created by dumping lead ore inside a furnace along with charcoal. However, it seems as though the lead was not used that often in the ancient past. The main problem was that it is too soft to be used to create a structure or forge weapons.
