Van Gogh Painting Losing Its Luster
"Flowers in a Blue Vase," owned by the Kröller-Müller Museum in The Netherlands, is showing signs of deterioration. Specifically, the brilliant yellows are beginning to crack and turn gray.
The museum stated in a press release that it decided to take two tiny samples from the painting and have them analyzed. Imagine being charged with the task of popping off pieces of a Van Gogh painting! Anyway, the samples were sent off to a laboratory that found that a varnish added to protect the painting after the artist's death included lead that reacted to cadmium in the yellow paint to gradually turn the paint gray.
Even more worrying, the varnish seems to have absorbed some of the underlying paint, thus making it hard to remove without causing damage to the picture. Now other museums owning Van Goghs will need to check to see if this type of varnish was used on their art treasures.
Koen Janssens, who led the research team, stated that, "paintings by Vincent Van Gogh are not static entities for decades and centuries to come. Over a period of 100 years, they can actually be considered a fairly reactive cocktail of chemicals that behaves in unexpected manners."
