ResumoFor decades archaeologists have struggled with the problem of accurately determining organic and mineral-based paints in pottery from the American Southwest. Using Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS), we have developed a simple and cost-effective method that permits classification of painted surfaces into mineral and organic-based categories. By applying this method to Mesa Verde and Mancos Black-on-white pottery from the Mesa Verde Region, we were able to distinguish easily between mineral and organic-based paints. Preliminary data also suggest that multiple sub-groups of mineral-based paints exist within these ceramic types, indicating that multiple recipes for manufacturing paint may have been employed by prehistoric potters from this region.
