There have been a few mentions of using CMC photographically but I haven’t seen a single one where the process is explained and given out. Anyway, I made my 10% gum arabic beer look-alike… I’m using a tiny spoon of sodium benzoate since I got no use for that now and its supposed to preserve things. Plus it does seem to harden the stuff in UV exposure. Then I went to make the 2% CMC mix… oh my god, just leave it there for a day, that stuff does snot (pun intended) want to mix! So I grabbed a long plastic spoon and hooked it up to my drill. That works! Definely if you add more water eventually the CMC material will be more watery.
