Noteworthy among the ceramics produced by these groups are escudillas, deep dishes painted in red and decorated in black with geometric figures, human faces and above all very stylized camelid motifs. Other typical ceramic forms of this period include large orange-surfaced vessels or jugs with face designs molded onto their necks, and geometric motifs painted in red or black. The Copiapó people were also expert metallurgists, using copper smelting techniques to manufacture earrings, bracelets and brooches, as well as axes and chisels. They also made necklace beads from copper and seashells, textiles from camelid wool, bone spatulas, and wooden tubes and tablets for inhaling hallucinogenic substances. These they adorned with a variety of engraved animal and human figures. They also made baskets and used woodburning techniques to burn designs onto gourds and bone artifacts.
