when I say it's not a casing glass, I mean it is not an intense color than thins well.
Green is not a good color to find in your red. Pale blue, yes. Wheat, yes but not green.I usually associate that with having tried using white tin, not black tin. The former is an opacifier and the latter a reducing agent. White tin ain't gonna make a red. It does make insanely tantalizing streaks of red though.
"so you'll have all the answers when I'm stumped." hah! Maybe dave, not me. I will however offer condolences.
And, you aren't going to get a white out of cullet unless of course it's white cullet. Then it isn't going to fit.
