   Scientists Replicate Color-Shifting Glass of Lycurgus Cup

   Researchers at the University of Sheffield have figured out how to recreate the 1,600-year-old glass recipe of the famous Lycurgus Cup. Dating back to around 400 CE, the ancient Roman masterpiece is made of dichroic glass and is notable for exhibiting different colors depending on the light, shifting from green to red. A university technician successfully reproduced the remarkable color-changing effect in quantity for the first time in 1,600 years, cracking a long-standing scientific mystery regarding how the ancient artifact was manufactured using early nanotechnology.

   Why it matters

   The Lycurgus Cup has baffled experts for decades because of its unique optical properties, which stem from microscopic particles embedded in the glass. Recreating this ancient technology provides insight into advanced manufacturing techniques used by Roman artisans centuries ago. Researchers utilized the newfound recipe to craft a sculpture that mimics the exact light-shifting phenomena of the original British Museum artifact.

   What is confirmed

   • University of Sheffield researchers figured out how to re-create the 1,600-year-old glass recipe used in the Lycurgus Cup.
   • The Lycurgus Cup dates back to around 400 CE and is made of dichroic glass that exhibits different colors depending on the light.
   • A University of Sheffield technician successfully reproduced the remarkable color-changing effect in quantity for the first time in 1,600 years.

   What to watch next

   • Further publication of the exact chemical formula and manufacturing steps by the University of Sheffield team
