| Summary: | Archaeometric, physical, and chemical studies provide information regarding components of clay, paints, slip, and, specifically, the decoration process with graphite in Aguada Portezuelo ceramics. These data contribute knowledge about the current nature of these elements, guiding the identification of possible raw materials and their treatments. Although existing literature describes the physical and chemical behaviour of materials under controlled conditions, the study emphasizes the need to complement it, considering the impact of variable factors such as varying firing atmospheres and unknown proportions of components in ceramic pastes as well as in preparations for pigment mixtures. This research not only seeks to replicate white slips and surfaces with graphite decoration inspired by archaeological analyses of Aguada Portezuelo, but also to assess the impact that the shapes of the pieces' walls had on the final results. The approach includes evaluating the adherence of white slips, taking into account their fragility in archaeological records, and exploring the application of graphite decoration on exterior surfaces of vessels and on flat surfaces (briquettes). The ultimate goal is to improve the understanding of ceramic production in Aguada Portezuelo, shedding light on the decorative practices employed by artisans of that time. |
