In association with the investigation of Albenda (preceding paper) fragments from four polychrome glazed terracotta wall plaques (knob plates) were submitted for technical examination. All are believed to date to the ninth century B.C. and represent three sites: Nimrud (WA 131663), Ba'shiqa (Tell Billah) (WAN 2037, N2038) and Arban (WA91689). Technical information on the glazed ceramics of the Neo-Assyrian period is limited. In addition to providing basic information on the ceramic technology of the plaques, the purpose of the present study was to determine if stylistic differences noted between the ceramics from the three sites were in any way reflected in their technologies.
The plaques were examined using a binocular microscope, and small (millimetre-sized) samples of glaze with associated body were removed from the edges of the fragments. These samples were mounted in epoxy resin, ground flat, polished with diamond paste and the resulting cross sections examined in the scanning electron microscope (SEM). Elemental compositions were determined by energy dispersive x-ray analysis (EDXA) in the SEM.
