Pigment studies on porcelain painting may help to support the attribution of a special artefact made from porcelain to a certain artist. Examinations of a variety of decoration details allow a representative image of the paint materials used. Non-destructive substantial analysis is guaranteed by X-ray (PIXE) and gamma-ray (PIGE) emission plus particle backscattering (RBS), induced by the proton beam at atmospheric pressure.
