Rigoberto Mateos Campechano from Tonalá, Jalisco, works primarily with barro negro (black clay) to create a wide variety of decorative and functional pieces. His work includes decorative vessels, crucifixes, animal figures, suns and moons, pre-Hispanic masks, and skulls in different sizes. He also creates clay mosaics mounted on wood or steel bases, as well as jewelry, ashtrays, and Xoloitzcuintli (Mexican hairless dog) dog figures. Many of his pieces combine traditional claywork with wood or metal.
