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.

The surface of the two engobed sherds, fragments of unfinished products, indicates that at least two firing processes were used. Two samples show characteristics of Byzantine pottery, and three of them can be classified as Islamic ware or maiolica, whilst the other one displays intermediate characteristics. The variety of ceramic wares indicates the presence of craftsmen with differing expertise, and suggests that part of their work was dedicated to experimentation on new ceramic production techniques.
