The scanning proton microprobe and electron microprobe/microscope are used to characterise overglaze painting on 18th and 19th century Japanese porcelain. The first objective was to distinguish between two apparently different types of gold painting in terms of particle size, composition and application. The multi-element X-ray mapping and analysis using proton-induced X-ray emission and the depth profiling possible using Rutherford back-scattering on the scanning proton probe make simplify the analysis of the structure of complex decorative schemes involving several pigments. First results and future developments are presented.
