I've been experimenting with cobalt blue, even at 1/2 percent it's very strong colouring and I want to produce something much more subtle (hopefully saleable!), like a sort of pale duck-egg blue or pale grey-blue, perhaps even with a tiny hint of jade to it.
I think I will have to reduce the cobalt down to something like a quarter or an eighth of a percent.
I will soon be firing some more test pieces with differing percentages of oxides this week and hoping someone can give me some ideas, to help set me in right direction.
If it was a paint, I'd just be adding a little grey or pale green I suppose, but with glazes I'm finding most don't seem to do what I expect!
Appreciate very much any ideas to set me on the right sort of path!
By the way my kiln is electric oxidising and firing to 1230 with 45min soak.
