ABSTRACTEnamels from European Renaissance enameled gold jewelry and other objects dating from the sixteenth and seventeenth centuries, and Renaissance style and other objects from the eighteenth and nineteenth centuries were quantitatively analyzed using energy dispersive X-ray spectrometry. Differences were observed in the overall compositions, as well as the colorants and opacifiers used, of the Renaissance period and most of the later enamels. Some enamels from as late as the early nineteenth century, however, appeared to be essentially the same as those used during the Renaissance. The differences found in the enamel compositions can provide a set of objective compositional criteria to help distinguish between authentic Renaissance period enameled objects and some later enamels done in the style of the Renaissance.

Handheld portable energy-dispersive X-ray fluorescence (pXRF) spectrometry is used for non-destructive chemical characterization of archaeological ceramics. Portable XRF can provide adequate analytical sensitivity to discriminate geochemically distinct ceramic pastes, and to identify compositional clusters that correlate with data patterns acquired by NAA or other high sensitivity techniques. However, successful non-destructive analysis of unprepared inhomogeneous ceramic samples requires matrix-defined scientific protocols to control matrix effects which reduce the sensitivity and precision of the instrumentation. Quantification of the measured fluorescence intensities into absolute concentration values and detection of light elements is encumbered by the lack of matrix matched calibration and proper vacuum facilities. Nevertheless, semi-quantitative values for a limited range of high Z elements can be generated. Unstandardized results are difficult to validate by others, and decreased analytical resolution of non-destructive surface analysis may disadvantage site-specific sourcing, jeopardize correct group assignments, and lead to under-interpretation of ceramic craft and production systems.
