This paper describes the preliminary results of a study of the paint layers in 17th-century paintings
belonging to the collection of the Wilanow Palace Museum. The works chosen for examination are of great
importance to the Museum, as they might have been painted by court artists of King John III Sobieski.
The aim of the study was therefore to determine the technological structure of the paintings, to determine the
scope of conservation interventions and, above all, to gather comparative material that would serve to conduct
further multidisciplinary attributive research.
The presentation relates to studies in which laser-induced breakdown spectroscopy (LIBS) and optical
microscopy were used as diagnostic tools.
LIBS is based on the evaporation of a small amount of the material under investigation, and the generation of
plasma which emits continuum and line radiation. The analysis of line radiation allows us to identify the elements
appearing in the sample being investigated. The microscope pictures were taken using a Bresser Digital Hand
Micro 1.3Mpx and the Hirox 8700 microscopes.
The results obtained have confirmed the utility of the LIBS method in the study of artworks. They have also
proven that it can be used as a method to complement microchemical analysis, as well as an method to identify
and examine artworks from which samples cannot be taken, as it is micro-destructive and the analysis can be
conducted directly on the object, without the need to take samples.
