From the archaeometric point of view, very few studies have been performed on late antiquecopper-alloys, mainly by means of destructive techniques.The present study opens up newperspectives of research in this field. The materials include personal ornaments (e.g. finger rings and buckles) and furniture decorations (e.g. decorative objects for cabinets and tables) from three main archaeological sites of Puglia (southern Italy): Faragola, San Giusto and Canusium.Major aims of this study are the characterisation of the alloy and corrosion products and the reconstruction of the production technology by TOF neutron diffraction. The historical importance of the pieces makes the adoption of a completely non-destructive technique mandatory.
