Dramatic before & after How do we clean a 600-year-old painting | Uccello's Battle of San Romano

Restorer Paul Ackroyd talks us through some of the challenges he encountered while working with Uccello's 15th-century battlefield scene. Paul assesses the 'before' state of the painting and shows us how, after removing the discoloured varnish, the gleaming whites and shiny silvers emerge. 🎨 Find out more about 'The Battle of San Romano' Website link: 🎨 Find out more about Paolo Uccello Website link: 🎞 Subscribe to our YouTube channel and never miss a video: Follow us on social media! ⭐️ Twitter ⭐️ ⭐️ Instagram ⭐️ ⭐️ TikTok ⭐️ @nationalgallerylondon ⭐️ Facebook ⭐️ Help keep the museum accessible for everyone by supporting us here: The world's greatest paintings to your inbox.
