Wall painting with animal decoration (Cástulo, Linares, Spain)

Wall painting fragment from the room 6 (building D, area 2) of the Roman site of Cástulo (Linares, Spain). The goat depicted could be likely the Goat Amalthea. The analysis performed by MRS and EDXRF shows the next results: red decoration was manufactured with hematite (Fe2O3), yellow decoration with goethite [FeO(OH)] and white decoration with calcite (CaCO3).

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.
