Praseodymium Glass?

  1. Mar 11, 2010 #1
    Could a powder of praseodymium glass be used as a yellow-green pigment, which have historically been rare and very lightfast?

    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.
