RE: ferric oxalic

It may help with some aspects of the solution. I have not been adding it to mine, as I make my own liquid from scratch. The few times that I did add some, there was a solid that formed at the bottom of the bottle. At this point I don’t recall if it was just with some B&S that was kicking around the studio then, or if I tried it on several samples; B&S, Formulary, possibly some of Mine, Artcraft, … The solid however, would NOT dissolve in hot water alone; even boiling water.

What about the addition of EDTA while mixing, or is that no longer recommended?  It has seemed to help mine dissolve.... or it could have just been the oxalic.
