This analysis seeks to examine the potential link between innovations in clay technology as a building material with the parallel development of pottery technology. In particular, we would like to investigate the trajectory of firing methods in the technological sequence at Chavín de Huantar, Peru. Through Scanning Electron Microscopy (SEM), we will examine vitrification structures in the sherds and fragments refired to a known temperature to estimate both the original firing temperature and the optimal firing range (maturation temperature) for the paste recipe. To this end, we mined clay from a location near the site and exported a collection of 250 sherds for analysis. We intend to address such questions as: Is the firing technology different between Chavín sub-styles? Is there evidence of technological phases? Can technology distinguish between locally made vs. imported Chavín? Is the Huarás style technologically distinct from the preceding Chavín styles?
