ACKNOWLEDGEMENTS

The authors would like to thank Mr. Richard Moore of Bonfoey Company in Cleveland, Ohio, and Mr. Kenneth B� of the Cleveland Museum of Art for donating some heavily fire-damaged paintings for our testing and also for providing very helpful comments, discussion, and advice. We would also like to thank Father Bob Weaver and the members of St. Alban's Episcopal Church for providing information about the Madonna painting and for their interest and enthusiasm surrounding its cleaning.
