STEFAN MICHALSKI graduated in 1972 with an honors B.Sc. in physics and math from Queen's University, Kingston, Ontario. From 1977 to 1979, he trained as an artifacts conservator in the master of art conservation program of Queen's University. Since 1979, he has been employed at the Canadian Conservation Institute, currently as senior conservation scientist. He is consultant to Canadian museums, libraries, and archives on preventive conservation and a researcher in physical aspects of deterioration and conservation processes. Address: Canadian Conservation Institute, 1030 Innes Road, Ottawa, Ontario, K1A OM5 Canada.
CAROLE DIGNARD graduated from the University of Ottawa with a B.Sc. in physics and Italian in 1981 and an honors B.A. in classical studies in 1983. She received a master's degree in art conservation from Queen's University in 1986, specializing in the conservation of objects. In 1987, she was a J. Paul Getty Fellow at the Peabody Museum of Archaeol-ogy and Anthropology, Harvard University. She has been working in the objects section of the Canadian Conservation Institute since 1988.
