This is powerful, yellow paint, made with one of the older lake type pigments, Arylide.
Arylide pigments work exceptionally well in oil paint, ticking all the boxes, lightfast, powerful, transparent, non-toxic and they handle well.
I have never tried this particular paint in glazes, however it could be exceptional, as it will bounce a lot of yellow light around and it is truly transparent.
A tube of this will last a while given the high pigment load and if luminescence is what you are after then you have found it.
"An Arylide organic lake pigment, of itself very fat and transparent, but which has an enormous tint power, shooting right through mixes with a pervasive range of bottle green undertones. Beginners should handle it with care when adding it to other paints! It can heighten the Phthalo lakes without making them opaque, and when it is made itself opaque with the addition of white the results are almost luminous."
