‘It’s magic’: scientists rediscover how to make ancient Roman colour-changing glass
Scientists at the University of Sheffield have recreated the color-changing effect of the ancient Roman Lycurgus Cup, a 1,600-year-old glass artifact that shifts from green to red depending on the light. They used an old recipe and embedded gold and silver nanoparticles to achieve the effect. The discovery helps explain a long-standing mystery about Roman glassmaking techniques.
Scientists recreated the color-changing properties of the Lycurgus Cup by using an ancient recipe and embedding gold and silver nanoparticles in glass. The cup changes color based on the light source, a feature that has puzzled experts for centuries.
