Abstract: | Wallpainting fragments from the Caliphal Baths of Cordoba, Spain, were studied in this work for the first time. X-ray diffraction (XRD) and Raman microspectroscopy allowed the chemical nature of the pigments used by the Arabic artists of the time to be identified. All pigments were applied over a gypsum priming layer. The white, red, and yellow colors used were obtained from gypsum, hematite, and goethite, respectively. Some pigments were prepared by mixing these materials. The analytical techniques used also allowed the mortar material to be identified. The results of this study may be useful to develop effective conservation strategies for archaeological remains. |
