Protection of works of art from damage due to photochemical smog: progress report through September 1985

Experiments conducted in the early 1980's on a very small selection of modern artists' pigments showed that several pigments will fade dramatically if exposed to ozone at the levels found in Los Angeles photochemical smog. The objective of this research project is to provide a comprehensive assessment of the full scope of this fading hazard to works of art, and to determine the methods that can be used to protect works of art from damage due to photochemical oxidants. In order to achieve this objective, research is progressing on several fronts. Accomplishments to date will be summarized briefly, followed by several appendices that provide more detailed information on some aspects of the research.
