Someone posted a question yesterday about their unsatisfactory
soda-fire results, but it vanished before I could hit the reply button.
Often, lots of 'cold' color is a result of fast cooling, which
traps the dissolved iron in reduced (black) mode. I found that when cooling
the soda kiln, the slower it cooled, the brighter and warmer the color.
Further, I have found that starting the kiln up around 1800F and holding
there in OXIDATION for 2-6 hours will often produce very bright color. see
"Shinos in the Fire" in the Sept issue of CM.
Perhaps this does not apply to your case, but consider it.
