Ceramic vessel 1021. Cemetery Cerro de los Vientos (Baeza, Jaén, Spain)

Ceramic bowl recovered from ritual estructure 28 of the cemetery Cerro de los Vientos (Baeza, Jaén, Spain). Handmade ceramic, reducing atmosphere. It shows a geometric red and yellow exterior decoration.The physical-chemical analyses carried out by MRS revealed that the red decoration was manufactrued with hematite (Fe2O3) and the yellow one with goethite [FeO (OH)].

Elemental analysis by EDXRF confirmed a high concentration of Fe (28.21 % wt for red and 26.07 % wt for yellow). The use of goethite implies a post-firing decoration since this mineral loses its yellow colour when the firing temperature exceeds 300 ºC.

Energy dispersive X- ray fluorescence (EDXRF)

An energy dispersive X-ray microfluorescence spectrometer (M4 Tornado, Bruker) was used for this paper (CICT, University of Jaen). This spectrometer is equipped with a microfocus X-ray tube with an Rh anode, a polycapillary lens for X-ray focussing, and a 30-mm2 energy dispersive detector (SDD). 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 25 μm was chosen at an operating X-ray tube voltage of 50 kV and intensity of 600 μA. The tube current was adapted for each sample in order to optimise the detection of X-rays.
