Ceramic vessel 0015019146 (Cástulo, Linares, Spain)

Iberian globular ceramic vessel from the Area 3 of the archaeological site of Cástulo (Linares, Jaén, Spain). Oxidising atmosphere. It is decorated with red lines and semicircles. The red color is manufactured using hematite (Fe2O3) in high concentration (21.10% wt of Fe). This leads to consider an extra addition of hematite in the clay mixture used in the decoration.
Content analysis by GC-MS identified the presence of native sulphur This compound can be connected with purification processes related to the cleaning of objects and the celebration of rituals.

Activities

Archaeometric analysis

Análisis físico-químico

Ceramic. Analysis of decoration and contents

University Research Center for Iberian Archaeology

Raman Microscopy

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;

Gass Chromatography-Mass Spectrometry

Pottery. Lipids analysis

Destructive method for the identification of the total lipid profile: fatty acids, sterols, wax esters, fatty alcohols, triacylglycerols, etc. Any remains of soil were removed with an electric hand-drill. The sample was then grinded to the appropriate size in an agatha mortar (0.25 mm). Extraction with a the mixture chloroform/methanol (CHCl3:MeOH) (2:1 v/v) assisted by ultrasound. Derivatization of lipids to trimethylsilyl derivatives (TMS). The reaction tales place at 70 ºC for 30 min using N,O-bis-(trimethylsilyl) trifluoroacetamide (BSTFA) with 1 % trimethylchlorosilane (TMCS). The sample is solved in cyclohexane and then injected in GC-MS. Chromatographic separation is performed applying an adequate temperature programme.

Gas chromatography-Mass Spectrometry (GC-MS)

The analyses were performed using a using a gas chromatography equipment (model Thermo TraceGC Ultra) coupled to a Thermo DC Q II mass spectrometer. Autosampler Thermo Triplus (CICT, University of Jaén). The samples were introduced by on-column injection into a 15 m x 0.25 mm I.D. fused silica capillary column, coated with poly(dimethylsiloxane) stationary phase with 0.1 μm film thickness. Helium was used as the carrier gas (purity 99.99%).
