Ceramic vessel 1 close to grave I245. Cemetery of La Noria.
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: 4.72 % wt of Mn. Both oxides are the result of the transformation of pyrolusite when firing temperature is set above 450ºC and below 900ºC.

Archaeometric analysis Physical-chemical analysis Ceramic. Analysis of decoration.
| |
Raman Microscopy Mineral analysis of the red and black 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 analyisis of the 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. |
