Ancient Chimu Breastplate (13 th Century AD) 13th century AD. A copper alloy Chimu breastplate, in fine conditionMetalworking picked up quickly in the Late Chimú periods. Some Chimú artisans worked in metal workshops divided into sections for each specialized treatment of metals: plating, gold, stamping, lost-wax, pearl, the watermark, and embossing wooden molds. These techniques produced large variety of objects, such as cups, knives, containers, figurines, bracelets, pins, crowns, etc. They used arsenic to harden the metals after they were cast. Large-scale smelting took place in a cluster of workshops at Cerro de los Cemetarios. The process starts with ore extracted from mines or a river, which is heated to very high temperatures and then cooled. The result is a group of prills (small round sections of copper, for example) in a mass of slag (other materials which are not useful for metallurgy). The prills are then extracted by crushing the slag, and then melted together to form ingots, which were fashioned into various items.
