Characterization of inorganic pigments used by selected painters by using ion microprobe and other complementary techniques

The aim of this chapter is to show results of the collaboration between the Croatian Conservation Institute (CCI) and the Laboratory for Ion Beam Interactions of the Ruđer Bošković Institute (RBI) established within the present CRP. The CCI is the central Croatian institution for conservation and restoration of cultural heritage objects. Prior to restoration/conservation, CCI performs a scientific analysis of an object, primarily to enable selection of the best strategy for its restoration/conservation. On many occasions, such analysis is also helpful to resolve issues such as clarification of authenticity and/or the maker of an object. The CCI has its analytical laboratory, which is fully dedicated to the analysis of cultural heritage and art objects. The CCI analytical laboratory is able to apply various microscopy techniques and photography methods, and is equipped with portable X ray fluorescence spectrometer and X ray radiography instrumentation. Access to complementary microanalytical techniques like Raman spectroscopy or ion beam analytical (IBA) techniques is provided through an already long and successful collaboration with the RBI. The RBI laboratory for ion beam interactions provides complementary analysis of layered microsamples by using IBA techniques, such as particle induced X ray emission and Rutherford backscattering, and for the miniature samples by using ion microprobes.
