Ceramic vessel CC13. Oppidum Cerro de las Cabezas

Ceramic vessel from a house (area Z1, sector C) of the Iberian oppidum Cerro de las Cabezas (Valdepeñas, Ciudad Real, España). Oxidising atmosphere. Decoration with red circle and red lines. The colour is manufactured using hematite in a relatively high concentration (9.77% wt of Fe according to teh EDXRF analysis). It is likely that only an iron-rich clay was used to make the decoration.

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;
