Barium Sulfate During Copper Anode Casting

The history of copper metallurgy is thought to follow this sequence First cold working of native copper then annealing smelting and finally lost-wax casting. In southeastern Anatolia all four of these techniques appear more or less simultaneously at the beginning of the Neolithic c. 7500 BC
