In soda, I have used iron sulphate on bisque and Ranger Clay (a brick clay from Trinity Ceramic Supply) . Iron Sulphate is a fun wash, it seems to need to be mixed up fresh, but this may be due to contamination.

I also use saturated solutions of epsom salts and calcium chloride. Don't mix these two as they react with each other and the calcium sulphate drops out of solution. I prefer Calcium Chloride. Nice dull calcium scumming.

I like loading the pots wet on wadding. The wadding helps protect the shelves from wicking fluid from the pots.

These soluble compounds while not unique in the studio do pose some new hazards as they are more reactive than your run of the mill ceramic chemicals. Read the MSDS sheets, and don't mix them with acids (boric acid) unless you are prepared for the reaction.

I use a saturated solution of soda ash, with a handful of Neph Sye thrown in.

Depends upon the clay. It is a good dip for dry parts of the kiln
and is good under shino. I started using this, when I realized
dipping off the top of the shino glaze bucket made the shino whimpy.
I also add solution to the shino bucket.

It doesn't work well on an iron baring clay. Comes out
burnt looking. On light clay, I get simliar colors as you would in a
soda firing.

I someitmes use the dip on unglazed refires. This is from CM

Soda ash water

^10 Redu

12 cups soda ash
3 gallons water.

Soda porcelain. Let dry for one week. Reduce after 1850*F.

I never waited that long and I added about a cup of Neph Sye. Don't
put your hands in it if you have any cuts. Otherwise, wear rubber
gloves and/or rinse your hands immediately.
