Synthesis of historical pigments for use in fine art

Popis výsledku v původním jazyce

Present work deals with synthesis and evaluation of physical and chemical properties of rosiaite, which can be detected in historical yellow pigment known as Naples yellow. Rosiaite is the mineralogical name of a white powder with chemical composition PbSb2O6. This compound in high purity was synthetised by solid state reaction in several calcination steps at temperatures of 600 and 850 °C. The phase purity of the final products was characterised by X-ray diffraction analysis. Based on Raman spectra, PbSb2O6 can be identified in selected artworks by Czech landscape painters from the turn of the 20th century. The colour parameters L*, a*, b* of the rosiaite applied into the linseed oil were calculated from the diffuse reflectance spectra of the VIS. Sun light resistance of the oil layers were tested in QSun chamber. During the first 165 hours, the colour layers significantly degraded and changed the colour from white to grey.
