Abstract

Within the framework of a wide study of pieces of cultural heritage from the Andalusian baroque period, synchrotron radiation techniques were used to characterize the metallic parts of mirrors and musical organ pipes. By using X-ray fluorescence (XRF) and X-ray diffraction (XRD) with micrometre resolution information was obtained which was relevant either in the conservation or in the identification of these pieces. By monitoring with micro X-ray diffraction (μXRD) the degradation process of the amalgam of the mirrors, the evolution of the corrosion products could be followed. The identification and distribution of trace elements of tin and lead phases forming the organ metal pipes was carried out with the aid of micro X-ray fluorescence (μXRF). This technique allowed for the quantification of the elemental distributions in the major and minor components, knowledge useful to improve the manufacture of modern musical organs.
