A fine pottery made on the Pacific coast of Mesoamerica, near the Mexico-Guatemala border, during early Post-Classic and Pre-Columbian times. It was traded over a wide area, from Nayarit in northwest Mexico to Costa Rica in the south, and was present in all but the lowest levels in the Toltec center at Tula. The glazed appearance of the surface of Plumbate Ware is due to the unusual composition of the clay from which it is made and to carefully controlled firing conditions. There was a high percentage of iron compounds and, upon firing, the ceramic surface acquired a hard, lustrous vitrified surface often with metallic shine. Its original point of manufacture was on the Pacific coast of Mesoamerica in the vicinity of Izapa
