As part of a long-term research project consisting of scientific investigations of the various types of glasses excavated at Nimrud, the author of this report undertook a study of three of the nine painted glass plaques included among the finds at Fort Shalmaneser. This research is being conducted in co-operation with Mr. J. J. Orchard who, in Part I of this paper, has illustrated the plaques and discussed them in detail. As is the case with so many Mesopotamian glasses, the objects involved here are very heavily weathered, which complicated matters greatly. Such objects are not only extremely fragile and difficult to handle, but also the original glass— where any remains—is completely obscured by decomposition products. Moreover, in this instance, because so few of these plaques have been found, it was not possible to remove samples for all of the experiments which might be expected to yield useful information. Nevertheless, despite these limitations, several interesting findings have come out of our experiments.
