Curie‐point pyrolysis gas chromatography/mass spectrometry has been applied to different model paint samples containing proteinaceous (egg yolk) and oily (linseed oil) media. Results of pyrolysis at 610°C are highly reproducible, and among the different pyrolysis products some compounds diagnostic for the different binders have been identified. The application of the method to real samples, i.e. from the oil painting ‘Ritratto’ by Giuseppe Nogari (1669–1763) and from the tempera paint on the ligneous roof of S. Giobbe church (16th century) in Venice, proves its effectiveness in the identification of binding media.
