The article is a bit overly kind to Roman genius. Romans didn't deliberately produce nanoparticles. I'm not sure about the silver, but gold added to molten glass automatically disperses (dissolves) into nanoparticles; it was a problem for glassmakers hoping for gold glass who ended up with rose glass. So this is less Anythkea mechanism and more dumb luck that the Romans deliberately harnessed.
The basic glassworking is incredible, though. Romans would cast multiple shells of glass together and carve out those 3D bas reliefs.
