Non-invasive analytical investigation of Mudéjar polychrome on the carpentry of Alcázar of Seville

Research reveals significant differences in the polychrome pigments used on two sets of carpentry from the Alcázar of Seville, suggesting variations in application timing. The study employed non-invasive techniques such as X-ray fluorescence (XRF), X-ray diffraction (XRD), and Raman spectroscopy to analyze the external layers of the wood without causing damage. This approach allowed scientists to determine whether the pigments were original or altered during past restorations. The findings highlight the importance of understanding historical modifications in preserving cultural heritage, particularly for Mudéjar-style architectural elements.
