Pottery use in the mining site of variscite Mines de Gavà (Barcelona, Spain) during the 4th millennium BC based on organic residue analysis

• Terrestrial animal adipose fats were identified in most of the vessels. The oldest evidence beeswax on pottery surface Iberian Peninsula. Alternative uses for detected fat and are proposed. Residue analysis usually concerns habitat or funerary sites. In this work, we have studied 21 vases from Mines Gavà (Barcelona, Spain) which constitute mining focused variscite during IV th millennium BC. main objectives determining degree preservation lipids context, identifying natural substances exploited vessels highlighting use day-to-day work at site, as well establishing if some part grave goods burials same mines. results obtained by combining molecular isotopic analyses showed that>70% containers investigated provided significant amounts lipids. A wide diversity organic processed comprising fats, plants was determined. Relationships found between shape their content highlighted role life. This not only exposes one evidences Peninsula, but also allows us to understand management resources a very specialized archaeological site activities.
