As part of a study of fluorescence of paint and varnish layers under ultraviolet light, the fluorescence of a number of pigments has been measured with a fluorescence spectrometer. Of the pigments studied, only zinc white, cadmium pigments and genuine madder appear to possess fluorescence of considerable intensity. The physico-chemical background of fluorescence in general and of fluorescence of pigments in particular is discussed.
