Analytical techniques applied to art and archaeology objects can give the opportunity of gaining information about their composition and, therefore, allow to answer questions regarding where, when orby whom such artefacts were made. Additionally, these studies can help us to understand the manufacturing processes and technologies, providing clues for interpreting the social, political, economic and cultural context of the civilizations involved. Such investigations are also valuable and,in some cases, fundamental for conservation, restoration and authentication projects .
In this work, we present a characterization of porosity and morphology of ceremics belonging from differente archeological sities using Small Angle Neutron Scattering , in order to correlate the characteristics (total volume and pore dimensions) of the ceramics found in several German and Italian sites with specific production techniques. SANS measurements of samples immersed in heavy water were also performed to investigate the role of closed porosity on the material structure, its behaviour/evolution during the firing process and its effects on the mechanical properties. Laboratory-made samples with different clays and firing conditions were also characterized inorder to compare them with the ancient ceramics.
