This study focuses on the management of raw materials used in early ceramics production (late Neolithic to early Bronze Age) in the north-eastern part of the Iberian Peninsular (Catalonia). The main aim of the study was to attempt to understand some aspects of the socio-economic organization of the ancient inhabitants of the area. The objective was not only to describe the archaeological material and put forward some economic and chronological hypotheses, but also to define some aspects of the social structures. Special consideration in this study was paid to the Bell Beaker finds and the work contains detailed scientific analyses of the finds. Spanish text.
