Ceramic vessel 8 close to grave 233. Cemetery of La Noria.

Ceramic vessel 8 close to grave 233 (burial mound H) of the Iberian cemetery of La Noria (Fuente de Piedra, Málaga, Spain). Oxidising atmosphere. The origin of the black color is an oxide of manganese identified by MRS as bixbyite/hausmannite (Mn2O3/Mn3O4) and verified by the EDXRF analysis: 0.53% wt of Mn versus 0.08 wt of the ceramic paste. Both oxides are the result of the transformation of pyrolusite when firing temperature is set above 450ºC and below 900ºC.

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.

Elemental analysis of red and black 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
