This paper aims to present a techno-functional study of lignite ornamental objects found during the Fedele excavations (1977-1980) in the Boira Fusca Cave (Cuorgnè, Salto-Turin, Italy). The site demonstrates a chrono-cultural sequence which extends from the late Palaeolithic to the Modern era. Particularly during the first phases of the Metal Ages (Chalcolithic to Early Bronze Age- c. 3400-1600 BC) the cave was a burial site, similar to others in the Alpine area. The technological study of manufacturing methods, based on a wide experimental base, and conducted with the aid of digital microscopy is focused on drilling and shaping techniques.
