A portable X-ray fluorescence device for in situ analyses of mural paintings

Within the context of a research program for studying with nondestructive methods the preparation and realisation techniques of mural paintings used in the Roman age, a portable ED-XRF device for elemental analysis has been set up. Preliminary tests have been carried out on two Roman mural paintings belonging to the Baia Archaeological Complex (Naples). Datable to different periods, the two paintings show different manufacturing and conservation states, thus representing a good test for verifying the ED-XRF device capability. In situ and laboratory measurements, performed on materials of different origin and nature, have permitted the determination of the pigments and the recognition of pollution traces

Analisi di fluorescenza di raggi X

Le misure di fluorescenza di raggi X sono molto utili per eseguire l’analisi elementale di qualsiasi oggetto. La strumentazione portatile usata consente di eseguire le misure in situ, dove l’oggetto è conservato, ed in maniera totalmente non distruttiva. L’esame autoptico dimostra che i reperti metallici sono costituiti da parti realizzate con materiali chiaramente diversi, alcuni fortemente corrosi e altri meglio conservati. Dalla successiva analisi EDXRF è risultato che le parti corrose sono in ferro, mentre le altre possono essere attribuite ad una lega a base di rame e zinco, corrispondente all’antico oricalco. The X-ray fluorescence analyses are very useful to carry out the analysis of the elements of any object. The portable instruments offer the opportunity to exam in a totally non-destructive way the object in the very place where it is preserved. The autoptic exam showed that the metallic remains consist of pieces made with obviously different materials some of which strongly corroded and other better preserved. The EDXRF analysis showed that the corroded parts are in iron, whereas the other parts are made with an alloy of copper and zinc, corresponding to the ancient orichalcum
