This volume offers an in-depth critical appraisal of the status of stone conservation research today, identifying areas of strength and weakness in the field as a whole. C.A. Price, a noted British archaeological conservation scientist, discusses recent research on the causes of stone decay as well as current preventive measures, assessment tools, and treatment durability. He also reviews current research on methods of evaluating the effectiveness of these methodologies and treatments. The book includes a comprehensive survey of the literature, draws from conversations with professionals in the field, and provides recommendations for increasing the effectiveness of research, including the improvement of training, symposia, research programs, and the establishment of conservation policy.
