X-ray fluorescence determination using glass bead samples and synthetic calibration standards for reliable routine analyses of ancient pottery

Abstract: This paper describes a new X-ray fluorescence determination technique that uses glass bead specimens and synthetic calibration standards to reliably analyze the compositions of silicic pottery samples in order to estimate the provenance of the pottery.

“…Each pottery shard was pretreated as follows: (a) fragments (approximately 1 g) were sampled from the edge of each pottery shard, (b) the weathered surfaces were removed using an electric rasp, (c) the polished fragments were pulverized into a fine powder with an agate mortar and pestle, and (d) the fine powder was preheated at 500°C for 2hr using an electric furnace for deleting the wet and the organic. The glass bead specimens were prepared by fusing a mixture of the powdered sample (0.400 g) and anhydrous Li 2 B 4 O 7 (4.000 g) as an alkali flux in a Pt–Au crucible (CS‐2 type, bottom inner diameter: 35 mm, Pt 95%–Au 5%) using a high‐frequency electromagnetic fusion machine (Bead Sampler NT‐2000, Nippon Thermonics Co. Ltd.) under the following conditions: preheat at 800°C for 120 s; melt at 1,200°C for 120 s; and melt at 1200°C for 120 s with agitation …”
