The petrographic analysis of the finds from Sha‘ar Efrayim was conducted in an attempt to gain a better understanding of the cultural interaction of the site with other regions. For this purpose, fifteen Chlacolithic-period and Early Bronze Age clay artifacts were examined and grouped according to the characteristics of the raw material. The results shed light on the different raw materials used for specific vessel types in various periods, and provide important data for further discussions, e.g., regarding trade patterns during these periods.
