Ceramic vessel E12-II. Cueva de la Lobera

Ceramic vessel from the third terrace of the Iberian santuary Cueva de la Lobera (Castellar, Jaén, Spain). Oxidising atmosphere. Decoration with red semicircles and lines. Red colour is manufactured using hematite (Fe2O3). The concentration of Fe (10.44 % wt of Fe according to EDXRF analysis) means the likely use of a rich iron clay for the decoration.

Mineral analysis of the red decoration

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

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.
