Radioisotope x‐ray fluorescence (XRF) analysis was employed in provenance and technological studies of luxury colourless glass vessels originating from 18th century glasshouses in central Europe. The results refer to Polish, Brandenburg and Saxon glassware. A number of discriminating elements were selected and certain correlations between some of these elements, characteristic for the specific recipes and glasshouses, were found. The content of lead in crystal glass is discussed, and also that of some trace elements constituting characteristic contamination of raw materials. Multivariate statistical analysis, such as cluster and principal component analysis, allowed the grouping of the examined vessels. Certain limitations of energy‐dispersive XRF for the analysis of historical glass vessels are also presented. Copyright © 2000 John Wiley & Sons, Ltd.

Wavelength-dispersive x-ray fluorescence (WDXRF) was used for the determination of carbon in coal and ash samples. A rhodium side-window tube was used for C Ka excitation and a synthetic multilayer crystal (2d = 12.2 nm) for excited radiation analysis. The samples, undiluted or diluted with boric acid, were pressed as layers of 0.16 g cm −2 thickness on to a boric acid support. The relative standard deviation was 1.8, 1.5 and 15% for undiluted, diluted coal and ash, respectively.
