Ceramics manufacturing is one of the older and intensive human activities in all civilizations, from prehistoric to modern ones. In addition, potteries are approximately ¿eternal¿ and all archaeological sites reveal their presence after an excavation. This occurrence makes these material very interesting from the archaeologists point of view. We propose a neutron diffraction study (TOF-ND) on a series of Neolithic findings (samples date back to a period between the 5500-4000 b.C.) coming from a Sicilian archaeological excavation in the middle-eastern side of the island. We aim, through this technique, to derive useful information about the mineralogical phases distribution in the samples and therefore to gain information about the manufacturing techniques and sites.
