Ceramic vessel 5. Grave 66. Cemetery of Piquía

Funerary urn from the grave 66 located in the Iberian cemetery of Piquía (Arjona, Jaén, Spain). Oxidasing atmosphere. Decoration with red bands. The red color is manufactured with hematite (Fe2O3). The high concentration of Fe (58.98% wt by EDXRF) indicates an extra addition of iron ore to the clay mixture used in the decoration.

Micro-Raman Spectroscopy (MRS)

Portable equipment: BWS445-785S innoRam™ Raman spectrometer (B%26WTEK, Inc., Newark, USA) with a 785 nm excitation laser (maximum power of 300 mW) and a 4.5 cm-1 spectral resolution. The Raman microprobe can be mounted on a tripod with motorized XYZ axis (MICROBEAM S.A, Barcelona, Spain) or on a microscope sampling stage (B%26WTEK, Inc., Newark, USA).

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
