F. Casadio, A. Bezúr, I. Fiedler, K. Muir, T. Trad and S. Maccagnola Pablo Picasso to Jasper Johns: a Raman study of cobalt-based synthetic inorganic pigments Journal of Raman Spectroscopy 43
The Raman spectra of 20 historical and modern reference samples of cobalt titanate green and cobalt violet artists' pigments were acquired to assist in the identification of unknown cobalt-based pigments in works by Pablo Picasso (1881–1973) and Jasper Johns (b. 1930). Some of the spectra are presented here for the first time. This research advances the knowledge of 20th century synthetic inorganic pigments used by artists and documents their usage in actual works of art.
