Abstract
The aim of this work was to apply several spectroscopic methods of analysis to study the decorated pottery fragments found in the excavations of the Medici Villa of Cafaggiolo, near Florence, and of the roman-medieval site of Ferento, near Viterbo. The results of the analysis performed on the samples coming from these sites have been compared with thin sections mineralogical examination of the same samples.
The main objective of the analysis, performed in the pottery fragments of two site of central Italy, has been to obtain information about the productive processes, the firing temperatures and the materials used in medieval and Renaissance period. Further purposes were to enrich the knowledge and the databases of pottery materials and techniques, to study the evolutions of the productive processes through the history and eventually to try to identify the elements that characterize the two examined Italian productions.
Micro-Raman technique doesn’t need a pre-treatment of the samples under test; moreover micro-Raman is a non-destructive molecular method of analysis recently widely applied in the field of cultural heritage. In this work the results of micro-Raman analyses of Cafaggiolo pottery are related. Moreover some mineralogical studies on the Cafaggiolo and Ferento potteries are proposed. The Cafaggiolo potteries were also examined by means of quantitative X-Ray Fluorescence analysis and X-Ray diffraction.
