I wonder if the more accurate title might be: Scientists Discover How Ancient Romas Made Color-Changing Glass. Meaning that I've seen many examples of glass that appears different colors under different circumstances, but apparently none that worked the way this cup does.
For those who don't care to be held hostage by the journalist as he forces you through a long winded narrative: gold and silver nano particles are embedded into the glass
The ancient artefact described also featured in a Jonathon Blow lecture, as an example of an engineering skill we lost for 1600 years: https://youtu.be/ZSRHeXYDLko?t=402
