Activation analysis of Turkish and Canadian clays and Turkish pottery

The Effect of Purification and Firing of Clays on Trace Element Provenance Studies

“…Also T4 (the red fraction) seems quite different from the rest of the Thrapsano clays. Clay beds with broad spreads have been reported in the past (Birgul et al 1979) although some others were shown to be homogeneous (Birgul et al 1977).…”

New methods of chemical analysis—a tool for the conservator

“…For the investigation of elemental composition of inorganic materials such as pigments, glazes, ceramics, glasses, metals, etc., the instrumental methods of X-ray fluorescence analysis (XRF) [32][33][34][35][36][37][38][39][40] and neutron activation analysis (NAA) [41][42][43][44][45][46][47][48][49][50][51][52][53] are often applied with great success. Identification of the radiation generated can be achieved by wavelength-dispersive (WDS) [32][33][34] and energy-dispersive analyzing systems (EDS) [34][35][36][37][38][39].…”

A Trace Element Analysis of New York Chert Sources

“…XRF has been most commonly applied to ceramic assemblages, including collections from Africa (Aronson et al, 1994;Jacobson et al, 2002), Syria (Bakraji, 2004), Turkey (Birgul et al, 1979), the Roman Empire (Devereaux et al, 1983), prehistoric North America (Elam et al, 1992), the Middle East (Grave et al, 1996), the Mediterranean (Grimanis et al, 1980), Mesoamerica , and ancient China (Yap and Tang, 1985), to name but a few applications (see also Bertin, 1975;Garrison, 2003;Herz, 2003;Whitbread, 2001 for summaries of trace element studies of ceramics and lithics). Less commonly, XRF has been applied to lithic materials, most commonly obsidian (e.g., Kunselman, 1991Kunselman, , 1998 since volcanic outcrops can vary significantly in terms of trace element chemistry over relatively short distances, and less often to non-volcanic materials (e.g., Jones et al,1996).…”
