Pottery and clay samples from various parts of Turkey were analyzed for fourteen elements using the x-ray fluorescence technique. Seven elements were used as variables in the multivariate statistical analysis treatment for grouping. Most of the pottery samples studied belong to the Early Bronze and Phrygian period excavated in Central Anatolia. Only some Phrygian pottery from Yalincak and Büyük Tümülüs showed a similarity in composition to the major clay bed in this area.
