We performed studies on the red colored spots, mainly taken from non-restored parts. MIMOS II Fe-57 M{\"o}ssbauer spectroscopy (novelty in art-pigment analysis) mainly reveals haematite and crystallized goethite in red colors. Electron microscopy can identify various layers of the original and overpainting of an artwork. The number of layers fluctuates between three and four chemically painted areas. The portable X-ray fluorescence analysis enables to reduce the pigment list to containing mercury (cinnabar), lead, zinc, iron and titanium. Infrared-lightirradiation visualizes the different age of the pigments.}, subject = {Materialcharakterisierung}, language = {en} }
