Zusammenfassung
A set of late Roman glasses found in the graveyards of Cubas de la Sagra and nowadays conserved in the Archaeological Regional Museum of Alcalá de Henares (Madrid) has been characterized. The glass set is from the Camino de Santa Juana site, located in the South of the Community of Madrid. The objectives were, on the one hand, to determine the chemical composition and the chromophores responsible for the the glasses colour, and, on the other hand, to evaluate their conservation state to select the best preventive conservation strategy for their deposit or exhibition in the museum. For the first part, 14 samples from both graveyards were analyzed. For the second part, samples of soil near the glasses were studied to determine pH, mineralogical phases and influence on the glasses deterioration. The research was carried out by using conventional techniques: binocular microscope, X-ray fluorescence spectrometry, X-ray diffraction, field emission scanning electron microscopy equiped with X-ray energy dispersive spectrometry and visible spectrophotometry. The results allowed the glasses archaeometric contextualization in the whole late Roman ensemble of glasses of the Iberian Peninsula that have been analyzed by X-ray fluorescence and X-ray energy dispersive spectrometry up to now.
