ResumoAbstract This paper explores the application of Raman spectroscopy to the examination and analysis of a range media commonly found on works of art on paper. In this case all of the works are from the National Gallery of Australia's collection. Discussion specifically focuses on the practical benefits that a detailed knowledge of inks and pigments can have for both conservators and curators. Through the use of several case studies, different aspects of these benefits are highlighted. Consideration is given to the way in which Raman spectroscopy can supplement the commonly used technique of polarized light microscopy in the identification of inorganic and organic pigments. Comparative results using scanning electron microscopy–energy‐dispersive x‐ray spectrometry and Fourier transform IR microspectroscopy are also discussed. Works examined include an important but previously undisplayed pastel drawing by the Australian modernist painter Grace Cossington‐Smith, a sketchbook by the 19th century Aboriginal artist Tommy McRae and an early 20th century European lithographic poster.
