Tessera 0012001386-1. Cástulo (Linares, Jaén, Spain)

Blue glass tessera from the Mosaic of Los Amores, located in Building D of Area 2 at the archaeological site of Cástulo (Linares, Jaén, Spain). Raman analysis did not yield high-resolution data. However, elemental analysis revealed a high concentration of SiO2 (73.56 wt%), indicating the glassy nature of the tessera. The blue color was achieved by adding a small amount of Co to the glass paste (0.11 wt % CoO). The concentration of Sb2O3 (3.58 wt %) confirms the use of calcium antimonate as the opacifying agent for the tessera.

X-Ray Fluorescence

Elemental analysis

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

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.
