RAMAN IDENTIFICATION OF PIGMENTS IN THE WORK OF THE CHILEAN CONTEMPORARY VISUAL ARTIST IGNACIO GUMUCIO

The main pigments in the painting by the Chilean artist Ignacio Gumucio were identified by using micro-Raman spectroscopy. Three works by the artist, two paintings with wooden stand and a wall painting were analyzed. Pigments were vibrationally identified from cross-section samples of the contempora...
