The production of Nuragic Bronze Figurines represents a rich historical archive that provides key information not only about the iconography but also about the metal production and casting techniquesand on the development of the Mediterranean basin metallurgy [1].The period of their production is principally Early Iron Age (10th-7th century BC). The small bronze sculptures, made in lost wax, not always were cast in a single solution but, as can be inferred from a simple observation, most of the parts of the wax model were moulded separately and then joined. In the composition of bronze objects, one of the major difficulties was joining the different elements that make the form in its entireness. We propose to analyse three nuragic boat samples. The data obtained through this technique will permit to measure the phase composition and microstructural features of the metal matrix.
