Tessera 106. Erotes mosaic, Marroquíes Altos (Jaén, Spain)

Its colour is explained by the high Cu and Pb levels recorded, which clearly distinguish it from the rest of the glass samples. Its colour is explained by the high Cu and Pb levels recorded by XRF. The orange hue is generally attributed to the presence of cuprite (Cu₂O) crystals, while Pb is typically added to promote cuprite crystallisation and possibly enhance the glass’s brilliance. Minor amounts of Zn and Sn were also detected, suggesting the use of metalworking scraps—such as bronze or brass—as a copper source, or pewter as a source of lead

X-Ray Fluorescence

Elemental analysis

Non destructive. Surface cleaning. Sample pretreatment is not required. Direct measurement.

Portable Olympus Innov-X Delta Premium X-ray fluorescence spectrometer equipped with a rhodium (Rh) anode X-ray tube and a 20 mm2 SDD detector. An aluminum (Al) filter was applied to measure high-Z elements (from Fe onward) using a voltage of 40 kV and a current of 38.7 µA. Without filtering (low-Z elements), a voltage of 10 kV and a current of 50.8 µA can be applied. Measurements were performed in air for 150 s. The X-ray excitation beam was collimated through a window with dimensions of 3×3 mm2
