Tessera 7. Colonia Salaria (Úbeda, Jaén, Spain)

Green tessera from the Roman site of Colonia Salaria (Úbeda, Jaén, Spain). It belongs to an unidentified mosaic. Elemental analysis shows a major concentration of Si (67.92 wt%), Al (12.44 wt%), K (12.90 wt%), and Fe (2.15 wt%). Petrographic analysis reveals, consistent with the chemical composition, a mineralogy of the tessera composed of glauconite and iron oxides (alteration of glauconite).

Raman Microscopy

Mineralogical analysis

The tessera was sectioned to expose fresh, unaltered cross-section

Renishaw ‘in via’ Qontor Spectrometer coupled with a confocal Leica DM LM microscope (CICT, University of Jaén), equipped with a diode laser (785 nm, 300 mW), DPSS laser (532 nm, 50 mW) and a Peltier-cooled CCD detector, calibrated to the 520.5 cm-1 line of silicon.

X-Ray Fluorescence

Elemental analysis

The tessera was sectioned to expose fresh, unaltered cross-section

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.

Petrographic analysis

Visual characterization (5X handheld magnifying glass) and reaction with HCl to determine its carbonate nature. Preparation of a thin section.
