Discoloration paintings Van Gogh explained
ANTWERP - A complex chemical reaction forms the basis of the color of the yellow paint that Vincent van Gogh used.
The journal Analytical Chemistry published the results (14-02-11) of a study by an international team of scientists led by University of Antwerp. That yellow paint due some some discoloration to sunlight was in the 19th century allready known, but not all paintings have experienced the same varies degree of discoloration. Scientists previously suspected that the discoloration was related to the use of chromium in the yellow paint used by Van Gogh. Of the two paintings ''Field of Flowers near Arles" (1888) and "Bank of the Seine (1887)" was a microscopic piece of paint examined. In addition, the researchers have aged paint from old paint tubes, with a UV lamp.
