CHELMSFORD, Mass., Jan. 22 -- When Italy's National Museum of the Bargello, in Florence, decided to put Verrocchio's David on the road in the US, conservators wanted the 15th-century, four-foot bronze sculpture to look its best. Its recent restoration with an Nd:YAG laser not only revived the masterpiece, it also gave art historians a better look it. Nd:YAG MAKEOVER: A restoration using Nd:YAG laser technology altered art historian's interpretation of Verrocchio's David, now on exhibit at the High Museum of Art in Atlanta.
