Ceramic vessel 8. Horno del Guadalimar

Iberian ceramic vessel from the Horno del Guadalimar (Lupión, Jaén, Spain). Oxidising atmosphere. Decoration with dark red and light red/orange lines and bands. The red color is obtained using hematite (Fe2O3).The high concentration of Fe in the dark lines (44.33% wt by EDXRF) indicates an extra addition of iron ore to the clay mixture used for the decoration. The light red/orange color is likely made using a iron rich clay (8.46% 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.
