This paper presents studies and discussions of pottery-making practices during the Late period (ca. A.D. 900—1450) in Northwestern Argentina. It stems from an extensive archaeological research project carried out in the middle sector of the Abaucán Valley, Province of Catamarca, Argentina. Pottery production during this period is evaluated through the study of technological choices and technical identity, as well as its relationship to the technical behaviors developed by potters. The analysis of a large sample of ceramic sherds, complete vessels, and overfired sherds indicates that the potters produced a very narrow repertoire of ceramic forms (bowls, urns, and ollas) using local raw materials and technology, the latter with a strong hold in the area. Pottery production during the Late period was carried out in household contexts, becoming increasingly intensified and concentrated with the appearance of Inkas in the region. Additionally, some ideas are discussed concerning the technological choices of ancient potters during this period, and the implications for technological studies in archaeological ceramics.
