It will go amber/gold in salt firing, black in soda.
316 Kingman Feldspar (can use G-200 or Custer)
71 Red Iron Oxide
And there are a whole bunch more at Wikiclay. Here's another:
#2311 Sandra Johnstone Pumpkin glaze C1044 Kingman Potspar (try Custer of G200)
10 Barium carb
Add: 1 Red Iron Oxide %
*Base is in grams and doesn't total 100%
Ooops, though: barium. I don't keep barium in the studio; can't spare the neurons. What's that barium/ strontium substitution? Hmm, googling... Found it: .75 parts strontium in place of 1 part barium.
This one claims to be a shino for Soda/salt. I've never had good luck with that; I always get a washed out result. But wouldn't it be great! It's got Chris Gustin's name on it, which makes me more optimistic:
45 Neph Sy
11 F4 soda spar
15 Ball Clay
10 Calcined kaolin
4 Soda ash
Oh, okay, one more. These are better than bedtime stories!
#3165 Amber Celadon C9-10 Dark treacle brown
(lighter on porcelain or white stoneware). You can use it very thin for reddish accents in soda.
36 Albany slip (try Alberta slip)
22 Custer spar
3 Gerstley borate
I always have a psyche myself up a bit to mix glazes, as I find it tedious. But I'm inspired now!
