Application of energy dispersive X-ray fluorescence spectrometry to polychrome terracotta sculptures from the Alcobaça Monastery, Portugal
Portable energy dispersive X-ray fluorescence spectrometry (EDXRF) was used in the Alcobaça Monastery, in order to study the chromatic coatings applied to terracotta statues that belong to two seventeenth-century monumental groupings. The main goal of this scientific approach consisted in determinin...
