Praseodymium Glass as a Pigment?

[cuallito]

Could a powder of praseodymium glass be used as a yellow-green pigment, which have historically been rare and very lightfast?

The history section says that praseodymium glass is even rarer and costs even more. Do a Find on 1920 to find it.

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?

Hmmm, interesting! I wonder if this can be made into a pigment?

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