title: Analysis of the painting "Gioventú" (Eliseu Visconti) using EDXRF and computed radiography.
abstract: In this work, the painting "Gioventú" (Eliseu Visconti, 1898) was analyzed by means of energy dispersive X-ray fluorescence and computed radiography. A portable EDXRF system was employed to identify the pigments used by the artist: yellow, red and brown ocher; umber; vermilion; cobalt blue; lead white and viridian (or chromium oxide). The CR analysis revealed that the painting was in a good state of conservation and also a previous composition hidden under the painting.
