those made for ceremonial use for offerings at burials. Domestic pottery was developed without higher finishing, while funeral ceramics show more aesthetic refinement. The main features of Chimú ceramics were small sculptures, and manufacturing molded and shaped pottery for ceremonial or daily use. Ceramics were usually stained black, although there are some variations. Lighter ceramics were also produced in smaller quantities. The characteristic brightness was obtained by rubbing with a rock that previously had been polished. Many animals, fruits, characters, and mystical entities have been represented pictorially on Chimú ceramics. Archaeological evidence suggest that Chimor grew out of the remnants of the Moche, as early Chimú pottery had some resemblance to that of the Moche. Their ceramics are all black, and their work in precious metals is very detailed and intricate. Metallurgy Metalworking picked up quickly in the Late Chimú periods. The Chimú worked with metals such as gold, silver, and copper. 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, and crowns. 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, such as small round sections of copper, in a mass of slag, which are 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. The Chimú also shaped metals through hammering, as displayed in the image on the right of the silver Chimú beaker. Chimú metalsmiths achieved this technique with simple tools and a single sheet of gold. The artist would first carve a wooden mold. Then they would carefully hammer the paper-thin sheet of gold around the wooden base. Although copper is found naturally on the coast, it was mostly attained from the highlands in an area about 3 days away. Since most of the copper was imported, it is likely that most of the metal objects that were made were likely very small. The pieces, such as wires, needles,
