The formation of ceramic analytical groups based on compositional, technological, and stylistic analyses enables us to begin modeling the conditions of production and exchange that affected Hopi potters between 1300 and 1600 AD. The present study indicates that intervillage and intravillage production units can be isolated for pueblos located on adjacent mesas in northeast Arizona. Exchange of vessels between sites on and off the Hopi mesas suggests directionality, but there is little direct evidence that bears on hypothesized intervillage alliances of either potters' groups, kin groups, or elites. Previously determined analyses of over 130 clay samples and 132 sherds for 19 elements by neutron activation analysis (NAA) are published here for the first time.
