Ceramic vessel 104-2. Oppidum Puente Tablas

Ceramic vessel from the sanctuary of the Iberian oppidum of Puente Tablas (Jaén, Spain). Oxidising atmosphere. Decoration with red semicircles. The red color is obtained using hematite (Fe2O3).The high concentration of Fe (10.66% wt by EDXRF) indicates an extra addition of iron ore to the clay mixture used for the red decoration.

Micro-Raman Spectroscopy (MRS)

Renishaw ‘in via’ Reflex Spectrometer coupled with a confocal Leica DM LM microscope (CICT, University of Jaén), equipped with a diode laser (785 nm, 300 mW), and a Peltier-cooled CCD detector, calibrated to the 520.5 cm-1 line of silicon.

X-Ray Fluorescence

Elemental analysis of the red decoration

Non destructive. Surface cleaning. Sample pretreatment is not required. Direct measurement.

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.
