Is it green yet?

We're in the dog days of summer here in Las Vegas. Even with a swamp cooler running non-stop, it's often over 90˚ in my studio. Running the small test kiln nearly every day doesn't help.

I've just completed a large number of tests using the WaterFall Brown glaze base formula, but tweaking the colorants to come up with a green version. This photo will show you a little of the mania I'm experiencing; the test pieces in the front represent test # 105-112.



I've been consulting Robin Hopper's books, they contain a great deal of information about colorants and the various percentages needed to achieve the green that I want. Unfortunately, these last few batches- while they're close, they're not exactly what I had in mind.

It's back to the drawing board for me, but I've decided two things- I am going to write to Ron Roy, one of the originators of this glaze, and ask for help. And second- after one more round of testing, I am going to take a break. If I don't get the results I need, perhaps it's wise to take a breather.
