 Of particular note is that chemical analysis of ceramic fragments has revealed that the very same workshops not only produced the highest-quality Ik-style polychrome ceramics but also general low-quality ceramics for household use.High quality Ik-style ceramics made at Motul de San José have been excavated from across the Maya region, including Tikal and Uaxactún to the northeast of the city, Copán far to the south, and Altar de Sacrificios, Tamarindito and Seibal, in western Petén.A particularly rare feature found on Motul de San José ceramics is the so-called X-ray style, showing a figure wearing a mask but also portraying his face underneath it.
