Andean pre-Hispanic pottery forming 3D analysis: a pilot study from Quebrada de Humahuaca (Argentina) using digital methods

A pilot study using advanced digital methods reveals that paddling was likely employed to shape the body of a pre-Hispanic pottery vessel from Quebrada de Humahuaca, Argentina—a technique previously unrecognized in traditional pottery manufacturing in the region. Researchers analyzed a globular pot from the Pucara de Volcán site using 3D modeling via close-range photogrammetry and techniques like Morphological Residue Model (MRM) and Virtual Reflectance Transformation Imaging Visualization (V-RTI). These methods enhanced surface micro-topography visibility, identifying key macro-traces such as sub-circular depressions and horizontal pressure lines that correspond to paddling. The study also suggests coiling was used for the pot's collar. While the findings highlight the potential of digital techniques in pottery analysis, their accuracy depends on the precision of 3D models.
