The Prussian blue pigments were painted with linseed oil, as a pure pigment and mixed with white lead, (PbCO3)(2)Pb (OH)(2), zinc white, ZnO, or titanium white, TiO2, pigment. The samples were subjected to accelerated ageing for 800 h and the light fastness of the Prussian blue pigment was evaluated by reference to blue wool standards. Pure Prussian blue is extremely light fast whilst it strongly fades when mixed with a white pigment, especially with lead white or zinc oxide. The painted samples were studied by UV-visible, iron K-edge X-ray absorption, iron-57 transmission Mossbauer, and attenuated total reflectance infrared spectroscopy. X-ray absorption results reveal a decrease in the iron coordination number in aged samples in the presence of white pigment. The Mossbauer spectra of the pure Prussian blue and the unaged and aged mixtures of Prussian blue and lead white or zinc oxide at 1 : 100 and 1 : 10 dilution ratios, respectively, indicate the presence of iron(II) and iron(III) in a ratio close to one as expected for the bulk stoichiometric KFeIII[Fe-II(CN)(6)]; no change in the spectral parameters was observed upon ageing. Combined with the X-ray near edge absorption and infrared studies, these results suggest reduction of the surface iron ions in the Prussian blue with ageing upon exposure to light. 000015471 536__ $$0G:(DE-Juel1)FUEK412$$2G:(DE-HGF)$$aGrundlagen für zukünftige Informationstechnologien$$cP42$$x0 000015471 536__ $$0G:(DE-Juel1)FUEK415$$2G:(DE-HGF)$$aGroßgeräte für die Forschung mit Photonen, Neutronen und Ionen (PNI)$$cP55$$x1 000015471 588__ $$aDataset connected to Web of Science 000015471 650_7 $$2WoSType$$aJ 000015471 7001_ $$0P:(DE-HGF)0$$aSilversmit, G.$$b1 000015471 7001_ $$0P:(DE-HGF)0$$aSanyova, J.$$b2 000015471 7001_ $$0P:(DE-HGF)0$$aVekemans, B.$$b3 000015471 7001_ $$0P:(DE-HGF)0$$aSalomon, H.$$b4 000015471 7001_ $$0P:(DE-HGF)0$$aGilbert, B.$$b5 000015471 7001_ $$0P:(DE-HGF)0$$aGrandjean, F.$$b6 000015471 7001_ $$0P:(DE-HGF)0$$aLong, G.
