Nanogel technology restores Lichtenstein's 'Whaam!' at Tate

cultural-heritage · 2026-05-04

Roy Lichtenstein's 1963 diptych 'Whaam!', a Pop Art masterpiece housed at Tate London since 1966, has been successfully cleaned using a novel nanogel technology. For decades, conservators struggled to remove grime without damaging the delicate pigments and techniques. The breakthrough came via a chemical hydrogel developed by the Italian CSGI Florence consortium, which leaves no residue. The Tate's conservation team applied this gel to safely restore the painting's original colors, as detailed in a museum YouTube video.
