Abstract
Une série de perles d’ambre provenant de deux sites différents du nord de l’Italie ont été analysés par microscopie optique, par microscopie optico-numérique à haute résolution pour images en trois dimensions, microscopie électronique à balayage environnemental (MEBE ou ESEM) et par des moulages des perforations en silicone à haute résolution. Les moulages ont révélé que les perforations ont été effectuées à l’aide de poinçons chauffés au rouge, et ceci malgré l’abrasion à l’intérieur des perles causée par friction sur la cordelette. Nous avons également retrouvé un fragment de cordelette dans une des perforations, faite d fibres végétales entortillées, ce qui nous amène à discuter de son identification.
A set of Bronze Age amber beads from two different sites in northern Italy was studied by optical microscopy, digital microscopy for high-resolution 3D imagery, environmental scanning electron microscopy (ESEM) and high resolution silicone casts of the perforation holes. The casts demonstrate the use of a red-hot punch for perforating beads, in spite of the erasure caused by the string’s friction on the walls of the inner holes. We also report the find, within the perforation of one of the studied beads, of a cord fragment made of twisted vegetal fibres, and discuss the problems of its identification.
