フィラデルフィア美術館のインスタグラム(philamuseum) - 8月20日 06時36分

Happy 149th Birthday, #FlorineStettheimer! Born #onthisday in Rochester, New York, #Stettheimer became an icon of Modern art, creating exuberant paintings of the American Jazz Age using a vibrant palette. Unfortunately, some of the pigments Stettheimer chose can degrade over time. The detail in the second image shows a figure wearing a skirt that was painted with the pigment cadmium yellow. The arrow points to where the pigment has begun breaking down into whitish materials, lightening the bright yellow color. Under ultraviolet light, as seen in the third image, some of those whitish materials will appear bright orange. #PMAconservation #PMAScientificResearch
