Has anyone tried it? I bought some recently, interesting glass. Seems to be raku and a blue mixed. It's not striking as far as I can tell though so not sure on that, they say it reduces which I forgot to try. Rods range from cobalt, to striped brown/blue, to very very dark brown.
In my pic you'll see the range in rods and the glass, I bought .25 kilo and no two rods are alike. The dark turns to that dark blue you see in the bead, but very dark indoors.
It's listed in the transparents, but it's not as far as I can tell, even pulled into paddles, stringer yes.
