White phenomena on the surfaces of 24 unvarnished paintings by Willem Witsen
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 starch, while the other phenomena noted consisted of lead soaps and salts. This pape...

| description | 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 starch, while the other phenomena noted consisted of lead soaps and salts. This paper shows that starch and the lead components may have migrated from within the paintings to their surfaces, possibly due to unstable climate conditions in the past. |
