ICP-MS Isotopic Signatures of Lead Ceramic Glazes, Rio Grande Valley, New Mexico, 1315–1700
Published online by Cambridge University Press: 26 February 2011
Abstract
ICP-MS isotopie analysis of lead ceramic glazes suggests at least two sources were exploited by Ancestral Pueblo potters to obtain the lead raw material, presumably galena (PbS). Five Rio Grande lead glazeware sherds from the Sandia area and two found at Socorro share a common isotopie fingerprint. The temper of one of the Socorro sherds confirms an origin in the Sandia area; petrography of the temper of the second sherd does not tie to any known Socorro source rock. Two other glazeware sherds from Socorro have a distinctly different lead isotopie signature. A fifth Socorro glaze may be a mixture of the Sandia and Socorro lead source materials. The differences in lead isotopie signature thus accord well with mineralogical differences in the ceramic pastes. Lead isotopie signatures generated by ICP-MS analysis are a powerful new tool for grouping glazeware sherds, classifying individual samples, defining lead sources, and delineating trade routes.
