- What they did
- Scientists from the University of Sheffield recreated the ancient glass recipe to produce a modern sculpture that changes color depending on the direction of light, similar to the famous Lycurgus Cup.
- Why it matters
- This helps explain how nanoparticles of gold and silver added by Roman craftsmen affect how light interacts with the material, which was previously a mystery.
