AbstractThe fluorescence under ultraviolet light of oil-paints and some picture surfaces has been studied with a fluorescence spectrometer. The development of fluorescence and the yellowing of linseed oil appear to be greatly influenced by the presence of pigments. Some pigments have an inhibiting, some an enhancing effect, and some are indifferent. In the light of these results and the material published before, the fluorescence of some picture surfaces is discussed.
