Show moreCeramic Technology and “Cultural Borders”. The Example of Ceramic Decoration Techniques of two Postclassic Sites from the Malpaís of Zacapu (Mexico): Palacio and Malpaís Prieto Technical behaviors within the ceramic operating sequences may reflect sociocultural identities. Investigation of techniques, gestures, and know-how helps us to estimate whether the changes observed from one period to the other are endogenous (cultural evolution of the local traditions) or related to population changes. At the Malpaís of Zacapu, we use Postclassic ceramics to assess the possible arrival of a group of migrants in the thirteenth century. We aim to understand whether there is technological continuity between the Palacio (AD 900‑1200) and the Milpillas (AD 1200‑1450) phases. This study focuses on one aspect of the operating sequence: the decoration. The technological analysis discussed here highlights differences in the ceramic production between these two phases. These data support information from ethnohistoric sources that a new group of people arrived in the region during the thirteenth century. Show less
