Characterization and Identification of Natural Terpenic Resins employed in “<it>Madonna con Bambino e Angeli</it>” by <it>Antonello da Messina</it> using Gas Chromatography–Mass Spectrometry

Abstract

Abstract Background Natural resins were frequently employed as adhesives or as components of oleo-resinous media in paintings in the past. The identification of vegetable resins is still an open problem. The aim of this paper is to analyze by GC-MS some vegetable resins frequently employed in paintings, such as Venice turpentine, dammar, copal, elemi in order to identify their main component in raw and aged samples. Some molecules are proposed as chemical “markers” to identify these natural resins. Results The results obtained on standards allowed us to successfully analyze sample collected from one work of art: the Madonna with the Infant and Angels by Antonello da Messina (XV century). Conclusion The results obtained confirm that the painting the artist originally used a mixture of linseed oil and natural resin (Venice turpentine) as binding medium.
