Ceramic vessel 16-08. Oppidum Los Turruñuelos

Ceramic vessel from the Iberian oppidum Los Turruñuelos (Úbeda-Villacarrillo, Jaén, Spain). The site was linked to the battle of Baécula during the 2nd Punic War (208 BC). Oxidising atmosphere. Decoration with red bands and concentric semicircles. The red colour is manufactured using hematite (Fe2O3). The high concentration of Fe (42.67% wt of Fe according to the EDXRF analysis) indicates the adding of an extra amount of hematite in the clay for the red bands.

Energy dispersive X- ray fluorescence (EDXRF);

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;
