From January 22 to May 28, 2017, the Fondation Beyeler is exhibiting a rich trove of Impressionist artist Claude Monet (1840-1926). Months earlier, the foundation’s restorers had discovered an acrylic resin varnish on one of the water lily paintings, which required time and precise knowledge to remove.
Water lilies in a pond are a popular and famous subject of the Impressionist artist Claude Monet. They represent the idyllic nature of his own garden, where he sat and painted, capturing the clouds, trees and shore plants reflected in the pond in his paintings “en pleinair”. The work “Nymphéas” (1916-1919) also illustrates Monet’s art of painting and programmatic approach; it brings out the bright colors with a fine brushstroke and proves to be a characteristic part of his late work.
It was also “Nymphéas” that was kept under conservational examination in preparation for the current “Monet” exhibition at the Fondation Beyeler in Riehen/Basel. Head conservator Markus Gross and his team discovered a thin layer of acrylic resin varnish on the painting. This had been mistakenly applied to the water lily painting as part of an earlier restoration. In academic art, a painting was only considered complete when it was finished with a transparent varnish. But Impressionists, like Monet, increasingly dispensed with this final step and left their work as free as possible of any materiality other than its color.
The found acrylic resin varnish falsified the water lily painting rather than seeking its originality. The originally matt, pastel-like surface is now covered with a uniform, glossy film. In addition, the sensitive color harmony has been impaired, as the varnish creates a saturation that makes the colors appear darker and more contrasting. The difference becomes particularly clear when compared to other, untouched paintings by the French artist.
Time-consuming restoration
Removing the coating was not only a technical challenge for the restorers, but also a time-consuming one. The restoration work requires precise knowledge of both the properties of the varnish material and the original material surface. It took six months before a solution could be found to remove the layer. “We now apply a solvent that is bound in a gel. It remains on the surface for a short time, then we vacuum and rinse it off again so that the exposed painting remains intact,” says Markus Gross. The restorers were only able to uncover a few square centimetres before the exhibition opened on 22 January 2017. At a size of 2 x 1.80 meters, there are still a few more to restore.
