Watch as a 17th Century Portrait Emerges From 200 Years of Discolored Varnish | Colossal

Art historian, dealer, and BBC television host Philip Mould recently posted a video to his Twitter that reveals a gleaming 17th century painting hiding underneath two centuries of yellowed varnish. The protective finish is applied to protect paintings from wear, but over time will begin to discolor. In the short video Mould gently paints a solvent to remove this layer from the work’s surface, slowly brushing it away in circular strokes.
