Good work Kevin! Always question what you're being told are the limits.

A bit of potassium dichromate in with the manganese will do wonders for keeping the manganese in the state where it shows color. All my notes and books are packed up at the moment, so I can't supply a number, but I think Scholes lists a percentage for this addition in the color chapter if someone has their copy handy and can check.

If you want all your chemicals in one place at reasonable prices then check out:

They don't care what they ship.
They just added an annoying flash page as an entry. I hate that.

Pottery supply places will have a lot of these chemicals at higher prices. Davens Ceramics in Georgia is good and the prices not too bad.

There really is a huge range of blues and greens available by just changing the ratios of copper and cobalt. Some nice turquoise in there.

Different amounts of cobalt added to the manganese can give you a bit of a range in your purples too.

There's always sugar to get enough reduction for copper red, assuming getting the black tin is a problem.

A bit of copper in with cobalt gets you some different blues.
Art is not a's a way.
