Located on the western slope of Mount Fenera, the Eremita Cave overlooks the Alpine Sesia Valley in Piedmont region (Italy). Ten years of excavation (2012–2021) revealed that the cave was frequented for burial purposes during the Middle and Final Bronze Age (1600–800 BC) and yielded a ceramic assemblage composed of 2982 sherds. The petrographic study regarded 28 samples, selected by taking into account pottery typology, relative chronology, surface and core colours as well as macroscopic features of pastes. The analysis aimed at investigating paste composition and exploitation of natural resources. Pottery from Eremita Cave displays the characteristics of five fabrics, mainly discriminated by aplastic inclusions (quartz, granite-granodiorite, pyroxenite, volcanic rocks). These findings allowed to draw inferences on the Middle and Final Bronze Age pottery production in the Lower Sesia Valley and on the exploitation of local natural resources by human groups.
