Tessera P-12 (Cástulo Linares, Spain)

White 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). 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 a limestone rock for its manufacture.

Micro-Raman Spectroscopy (MRS)

Portable equipment: BWS445-785S innoRam™ Raman spectrometer (B%26WTEK, Inc., Newark, USA) with a 785 nm excitation laser (maximum power of 300 mW) and a 4.5 cm-1 spectral resolution. The Raman microprobe can be mounted on a tripod with motorized XYZ axis (MICROBEAM S.A, Barcelona, Spain) or on a microscope sampling stage (B%26WTEK, Inc., Newark, USA).

Elemental analysis

Non destructive. Surface cleaning. Sample pretreatment is not required. Direct measurement.

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.
