Tessera 0013008708-2 (Cástulo, Linares, Spain)

Black stone tessera from the Mosaico de los Amores located in the building D (area 2 of the archaeological site of Cástulo, Linares, Spain). The analysis by MRS shows the Raman spectrum of calcite (CaCO3) together with Raman bands of amorphous carbon (1376 y 1611 cm-1). EDXRF results present a high concentration of Ca (81.90% wt) indicating the calcareous nature of the tessera. Both results point out to the use of limestone rock for its manufacture.

Energy dispersive X- ray fluorescence (EDXRF)

An energy dispersive X-ray microfluorescence spectrometer (M4 Tornado, Bruker) (CICT, University of Jaen). This spectrometer is equipped with a microfocus X-ray tube with an Rh anode, a polycapillary lens for X-ray focussing, and a 30-mm2 energy dispersive detector (SDD). The sample chamber incorporates an XYZ motorized stage for sample positioning. A high resolution microscope is used to position the sample on the desired distance from the polycapillary. To increase the sensitivity of the low Z elements, the sample chamber can be brought under vacuum. For the analysis of the samples, a spot size of 25 μm was chosen at an operating X-ray tube voltage of 50 kV and intensity of 600 μA. The tube current was adapted for each sample in order to optimise the detection of X-rays.
