Museum conservationists research preserving phosphorescent and fluorescent art pigments

Preserving Unique Art Materials

Conservationists at the Indianapolis Museum of Art at Newfields are conducting research into the preservation of phosphorescent and fluorescent pigments. This work specifically addresses the materials used by designer Stephen Sprouse in his fashion collections from the mid-1980s, known for their graffiti prints and Day-Glo colors.

Research Presented at ACS Meeting

The findings of this research were presented at a recent meeting of the American Chemical Society (ACS) in Chicago. The goal of the conservation efforts is to understand how these pigments degrade over time and to develop methods to prevent their colors from dulling, thereby preserving the original vibrancy of the artworks.

Understanding Phosphorescence and Fluorescence

Phosphorescent materials, known as phosphors, absorb light energy and release it gradually as re-emitted light. This phenomenon has been recognized since the Middle Ages. Fluorescence, as seen in DayGlo paints, involves converting UV light into visible light to create brighter colors. Both types of materials have been widely used in various applications, from art and fashion to safety gear and industrial products.

Widespread Use of Light-Emitting Materials

Beyond Sprouse's designs, phosphorescent and fluorescent materials are integral to many everyday items, including glow-in-the-dark toys, fluorescent lamps, and traffic signage. Historically, DayGlo pigments were used during World War II for military applications, such as fluorescent fabric panels for ground troops and black light paints for aircraft carriers to aid night landings. Artists have also extensively utilized these materials, particularly in psychedelic art, since the mid-20th century.
