Non-invasive chemical and phase analysis of Roman bronze artefacts from Thamusida (Morocco)

A repertory of Roman military bronze equipment (1st– 3rd century AD) found at the archaeological site of Thamusida (Rabat, Morocco) was analysed by non-destructive X-ray fluorescence and time of flight neutron diffraction (ToF-ND). Most objects are made of leaded alloys, where copper is combined with tin and/or zinc and, in six cases, to arsenic as well. A mixed technology was employed, making a limited use of “pure” semi-finished materials if compared with the large utilization of recycled materials (brass and bronze).
