Picta fragmenta. Archeometria della pittura parietale nei siti vesuviani

Il contributo propone una sintesi critica dello stato delle ricerche e degli studi sull'archeometria dei siti vesuviani: caso di studio, i siti vesuviani.The archaeometry of materials, in Vesuvian sample too, didn’t accomplish yet the transition to the archaeology of production: indispensable condition is, after the definition of a common code for all the archaeologists and specialists of the exact sciences, chemists and physicists, the setting-up of shared strategies. As a privileged case-study, for the amplitude and richness of the sample, the Vesuvian sites are waiting, still today, a coordinated and integrated project, able to deeply enhance its potential. The first objective to reach is the systematic characterization, on a large scale, not only of the pigments and the colours, but also of the composition of “tectoria”. Last aim, the definition of the technical base of the Roman wall painting, following a method that can be similar to the researches in progress on the pre-Roman wall painting.
