Some 24 sherds of pottery from the Late Assyrian site of Qasrij Cliff, and 43 sherds for Khirbet Qasrij, a post-Assyrian site a few hundred metres away, were submitted to the British Museum Research Laboratory. At Khirbet Qasrij, a kiln has been excavated and, in addition to the pottery, a fragment of vitrified lining from the fire-pit as well as possible clay and stone raw materials were provided. The samples were examined macroscopically, with a x10 hand lens, in thin section in the petrological microscope and a selection has been analysed by instrumental neutron activation analysis (NAA). The aim of this study has been to establish as far as possible the nature of the production of the pottery assemblages. We begin by establishing the sources of the raw materials of the pottery using NAA, then petrology and the occurence of any non-local types. We then move on to discuss the processing of these raw materials to form the pottery, and the degree of control exercised by the potters upon their final products.
