Chicago -- U.S. scientists say they've classified the composition profiles of 62 modern sculptures in what may be a way to identify, date and authenticate sculptures.
Researchers from Northwestern University and the Art Institute of Chicago said their accomplishment marks the first comprehensive survey of the alloy composition of a large number of cast bronze sculptures by major European artists from the first half of the 20th century.
The sculptures studied, from the collections of the Art Institute of Chicago and the Philadelphia Museum of Art, included works by Matisse, Picasso, Renoir and Rodin, among other masters.
