Perhaps you were talking about the discussion of pigment agglomeration that is commonly called “flocculation” which happens when your mixture is not stabilized (heat, pH, mixing, settling, etc.).
I feel like both words are almost kind of french but not really…
It is sort of discussed here: Bleaching earth
Not really - but it does talk about color remediation, flocculation, agglomerates, and condensation all in the same thread. Its forever old and a fuckton of posts.
Here is a laymen’s article on pigment flocculation/agglomerates its specific to paint, but the references it provides discussion of pigments in organic solvents, nanoparticles, and a smidgeon about the American standards for testing pigments and their various qualities.
Good luck with your quest against Alzheimers - that’s a bitch took my great grandma from me.
