After talking with George Vardy at Mason Color, I am convinced it was our base glaze that was causing all the problems. We are switching to a strontium based frit from Fusion which according to Mason should radically change how responsive their stains are. Things are finally looking up. Thanks for your help and comments!!!

Ditto on the Reds - use the Cerdec inclusion stains. As for the
purples, I your base might be the problem, and/or perhaps you are not
using a high enough percentage of stain.
Always check the mason stain chart to see what chemicals to include
(usually zinc) or avoid in order to develop the color you want. Not
every base works with every stain. Some stains need a higher
percentage than 10%. Note that if you use ore than 10%, your glaze
might give you trouble.
Test test test!
