Black light, or UVA, has become an indispensable examination and documentation tool for cultural heritage professionals, but it might also trigger a reduction in the florescence emitted by cellulosic paper materials, surprisingly after only a few minutes of exposure based on previous studies. This project aims to define the onset of the fluorescence reduction, to understand if the reduction is a sign of chemical changes, and to relate this change to the long-term preservation of historic and artistic works on paper. Finally, the goal is to create a sensible and ethical set of practical guidelines for the safe use of black light on these cultural heritage artifacts.
