Scanning electron microscopy/energy-dispersive X-ray spectrometry (SEM/EDS) was used to characterize the composition of glazes found on a collection of blue glazed, white quartzite sculptures, excavated from 1913–1916 by the Harvard University–Boston Museum of Fine Arts Expedition at the site of Kerma, the capital of ancient Kush, in today's Sudan. The scientific analysis of these artifacts shows the experimental nature of this extremely rare manufacture which appears to have developed out of faience technology.
