Effetre Uranium Yellow is a soft, yellowish green opaque. There's also, just to confuse things, another Uranium Yellow in the Effetre line, however that one is transparent and I haven't tested it yet.

This is a very soft colour that has a tendency to spread on top of other colours, and it is moderately reactive. Uranium Yellow has a very even consistency, and is not streaky.

When used with silver, Uranium Yellow loses its green-ness and looks very yellow. In the bead on the right, the silver leaf on top of Uranium Yellow is a cloudy pinkish brown colour. In the bead on the right, where I reduced and encased the silver, most of the brown colour has disappeared but the silver still looks faintly pink through the Clear. Neither of these reactions is all that attractive to me.

On top of Uranium Yellow, my reducing silver glass frit looks a little washed out and sad, and it has fumed the base bead to a lemony yellow colour. In the bead on the right, my TerraNova2 frit has developed some nice colour. My tentative position on Uranium Yellow is that it is a nicer base for striking silver glass than it is for the reducing colours.

On top of Tuxedo, Uranium Yellow separates and thins out at the edges, looking slightly translucent. In the bead on the right, you can see that the edges of the Tuxedo stringer dots and lines are faintly hazy and there has been a little bit of bleeding.

When Uranium Yellow is used on top of Copper Green, you can see some evidence of a bright turquoise bleeding into the stringer dots and lines, however this reaction is not evident at all when Copper Green is used on top of Uranium Yellow.

When Uranium Yellow is used on top of Opal Yellow, the Opal Yellow underneath blushes a pinkish orange colour, however this reaction is not evident when the colour positions are reversed, because in the bead on the right Opal Yellow looks just about as yellow as I've ever seen it.

There are no real reactions to note between Uranium Yellow and Ivory or Uranium Yellow and Peace.

Here's a fun organic bead with a base of Uranium Yellow.
