The preservation and study of metals in terms of the problems of deterioration and appropriate methods of examination and treatment increasingly involve collaboration between scientists and conservators. The sixteen essays in this volume focus on actual objects from a wide range of periods and cultures. Contributors include Thomas Chase of the Freer Gallery in Washington, D.C., on the technology of Chinese bronze casting; Paola Fiorentino of the Istituto Centrale del Restauro in Rome on the conservation of the equestrian statue of Marcus Aurelius; Knud Holm of the National Museum of Denmark on the restoration of nineteenth-century zinc sculptures; Ian MacLeod of the Western Australian Maritime Museum on the conservation of metals from underwater sites; and W. Andrew Oddy of the British Museum on the use of gold foil and wire during the Iron Age in southern Africa.
