Abstract:


Since ancient times many natural organic materials have been used in artistic and historic works as binders, adhesives, fillers and coatings. The identification of these materials is important not only for a proof of authenticity; for restorers and conservators it is essential to recognize the materials and technologies employed by artists and craftsmen. For identification and characterisation of the different natural organic binders spectrometric and chromatographic methods are well established. Recently, capillary electrophoresis has been introduced as an alternative technique to receive analytical information about the kind and composition of the binding media used in artefacts. These materials are waxes, resins, drying oils, animal glues and plant gums. In the present review the application of capillary electrophoresis in this area is discussed against the background of a general survey of the more common analytical techniques.
