Des phénomènes blancs présents à la surface de 24 peintures non vernies de Willem Witsen (1860-1923) ont été étudiés. L'examen microscopique a permis d'en distinguer cinq types. Les résultats d'analyse montrent que les sphères étaient constituées d'amidon pur, tandis que les autres phénomènes étaient constitués de savons et de sels de plomb. L’amidon et le plomb peuvent avoir migré de l’intérieur des peintures vers leurs surfaces, vraisemblablement en raison de l’instabilité climatique des anciennes conditions de conservation.White phenomena on the surfaces of 24 unvarnished paintings by Willem Witsen (1860-1923) were examined. Five types could be distinguished using a stereo-microscope. Analyses showed that the spheres consisted of pure st...
