Tessera 20. Tethys mosaic, Villa of Bruñel (Quesada, Jaén, Spain)

White tessera belonging to the Tethys mosaic of the Roman villa of Bruñel. It is located in the background of the mosaic. Raman analysis indicates the presence of calcite (CaCO3), and X-ray fluorescence shows a high concentration of Ca and smaller amounts of Si, Al, and K. The raw material used was therefore limestone.

Raman Microscopy

Mineralogical analysis

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

Portable Raman spectrometer (model BWS445-785S innoRam) equipped with a CCD detector, a handheld fiber-optic probe, an automated MicroBeam tripod, a benchtop stand for small samples, and a BAC151A camera (University Research Institute for Iberian Archaeology, University of Jaén). A 785 nm diode laser (300 mW) was used, with a spectral resolution better than 4.5 cm-1

X-Ray Fluorescence

Elemental analysis

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

Bruker Tracer III SD handheld XRF spectrometer (HERCULES Laboratory, University of Évora, Portugal). This instrument is equipped with a silicon drift 10 mm 2  SDD detector, and a Rh target delivering a polychromatic X-ray beam of 3×3 mm². Spectra were acquired with 40 kV and a current of 11 μA, for a life time of 30 s. This analytical method detects elements with an atomic number higher than 12.
