I started on my (small) batch today, and so far it's looking good. I did the liquid emulsion strategy with amaco Mexican clay. My clay had been sitting for a while so it was REALLY dry, I pretty much had to do it this way, presoaking until I could make a smooth mixture with a bamboo skewer.
Here with 3 tablespoons of equal parts KNO3, MGSO4, K2SO4, and CSM+B. (Phosphate soon to come) Even with all the ferts it turned out really smooth, like buttercream frosting, the trick is going to be getting it to where it's workable.
So glad you posted this!
