Tessera 5. Villa Cerrillo del Cuco (Vilches, Jaén, Spain)

Pinkish tessera belonging to the mosaic of the Roman villa of Cerrillo del Cuco (Vilches, Jaén, Spain). Elemental analysis shows a major concentration of CaO (54.94 wt%) and MgO (23.43 wt%), and to a lesser extent SiO2 (12.08 wt%), Al2O3 (3.64 wt%), Fe3O2 (1.97 wt%), and MnO (1.43 wt%). Petrographic analysis indicates a mineral composition consisting mainly of dolomite [CaMg(CO₃)₂], with minor amounts of Fe and Mn oxides. The raw material used in the manufacture of the tessera was, therefore, dolomite rock.

X-Ray Fluorescence

Elemental analysis

The tessera was sectioned to expose fresh, unaltered cross-section

EDAX (model Eagle III) fluorescence spectrometer (CITI, University of Seville). This spectrometer is equipped with a microfocus X-ray tube with an Rh anode, a polycapillary lens for X-ray focussing, and an 80 mm2 energy dispersive Si-(Li) detector. 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 300 μm was chosen at an operating X-ray tube voltage of 40 kV. The tube current was adapted for each sample in order to optimise the detection of X-rays.
