Yellow paint in the painting of Norwegian artist Edvard Munch’s “the Scream” eventually collapses due to high humidity. To such conclusion the team of scientists, conducted x-ray analysis of micron paint from the canvas, writes Daily Mail.

According to the researchers, is part of yellow cadmium sulfide is oxidized and fade in humid conditions. Previously it was thought that the cause of the deterioration of the quality of the picture is the effect of light on the canvas. That is why the “Scream” kept in a dark room and put seldom — only under controlled low light and 50% humidity. Based on the results of the new analysis, the effects of light on the picture is actually minimal.

Scientists have concluded that the placing of “Scream” on permanent display in the Museum level humidity should not exceed 45 percent. The level of lighting should be retained in the standard for the room with the paintings “light-fast” inks.

“This study shows that art and science are inextricably linked, and that science can help save works of art that the world can continue to admire them for years to come,” said Constance of Miliani studying art of the Italian National research Institute. It is noted that the cadmium sulfide is also used in the paintings of Henri Matisse, Vincent van Gogh and James Ensor.

Edvard Munch suffered from chronic anxiety. Under the influence of their emotions, the artist has created a composition “the Scream”, which became an expression of the “infinite scream of nature.” To reflect his emotional state, he carefully picked up the “flashy” bright colors. The author has created two versions of the image: one in 1893 and one in 1910. It is the second version of the painting have been explored and studied professionals. Now it plans to exhibit at the Munch Museum, which opens after a reconstruction in the Norwegian capital of Oslo.
