ALICE BOCCIA PATERAKIS has an MAC (master of art conservation) from Queen's University in Kingston, Ontario, Canada. Since 1986 she has been head of conservation of the Agora Excavations for the American School of Classical Studies in Athens, Greece. She has carried out research into the contamination of ceramics by soluble salts and the corrosion of copper alloys, with particular interest in determining the criteria for the formation and behavior of these compounds. Address: Agora Excavations, American School of Classical Studies, 54 Souidias St., Athens 10676 Greece.
