Is Khirbet Kerak Ware from Khirbet al-Batrawy (Jordan) local or imported pottery?

Abstract

A multi-analytical approach has been applied to characterize Khirbet Kerak Ware from the archaeological site of Khirbet al-Batrawy (Jordan), a highly distinctive pottery production of Early Bronze III Levant. Sherds of Khirbet Kerak Ware vessels, dating back to 2750–2500 B.C., show peculiar shapes and a highly polished red/black coating, alien to other Levantine ceramic traditions. Micro-Raman, infrared spectroscopic and petrographic data have been obtained with the aim of defining the fabric, tracing the origin of the raw material used in the manufacturing process and exploring the technological aspects. The results on Khirbet Kerak Ware are then compared with those of ceramics of the same period found at that site in order to highlight possible differences or similarities in the manufacturing process. All these pottery productions reveal similar mineralogical composition, compatible with a local sourcing of the raw materials; moreover, the identification of a specific mineral assemblage allows to estimate a firing temperature ranging from 850 °C to 900 °C. In spite of the marked differences observed between macroscopic appearances of Khirbet Kerak Ware and those of other coeval and local pottery productions, the results are indicative of overall local manufacturing.
