Ceramic vessel 10. Horno del Guadalimar

Iberian ceramic vessel from the Horno del Guadalimar (Lupión, Jaén, Spain). Oxidising atmosphere. Decoration with dark red semicircle and lines and light red band. The red color is obtained using hematite (Fe2O3).The high concentration of Fe in the dark lines (51.98% wt by EDXRF) indicates an extra addition of iron ore to the clay mixture used for the decoration. The light red color is likely made using a iron rich clay (7.77% wt of Fe according to analysis by EDXRF).

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.;
