I wonder what they are using to make that color of glass then? Silicates and aluminates usually make very good pigments; so I wonder why if they can make yellow-green glass so easily why can't they make a yellow-green silicate or aluminate?

I imagine it would but one would blend in a white opacifier and then grind the cullet to pigment-sized dimensions.
