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.
Regards, Hank in Eugene
