“Donatello’s David, the statue credited with starting Italian Renaissance sculpture, is to receive its first big clean-up using innovative laser lifting techniques that are expected to reveal striking gold leaf hair highlights. The 18-month restoration, boosted by €200,000 (£135,000) in government funding, will be carried out in front of visitors to Florence’s Bargello museum. Instead of moving the bronze figure to a laboratory, restorers have brought their lights, cleaning utensils, microscopes and lasers into the display room.”
