Loris, have you actually observed "dark effect"  in wet emulsion?  I'm skeptical whether is actually exists.

marek,
Our own clay harmon worked out a great method for working with it that
requires only a single coat with no more palladium solution required
than the same size print on cot-320. you add 1/4 of the emulsion again
in distilled h2o (so 18 drops palladium and 18 drops of ferric for an
8x10 is extended with 9 drops of h2o), after coating let it sit for 60
seconds, blow dry it to bone dry, then let it sit for to come back up
to ambient humidity--or you could just use a humidifier at this point.
the surface has a velvety depth that is just stunning.
