Authentication and characterization
Authentication using microanalysis and PIXE
The study of silver objects using scanning electron microscopy allows to detect possible voluntary surface treatments, and if, to highlight elements corresponding to modern metallurgy.
In parallel, measuring the trace-elements concentration with PIXE (less than 0.1%) indicates if the metal comes from ancient or modern silver metallurgy.
The scientific analysis of silver objects participates, in particular, to the reconstitution of the manufacturing processes and to provenance researches of raw materials.
