Can one add pure alcohol instead of Tween or Photoflo/Ilfotol to
facilitate coating of gum emulsion? Will alcohol get in reaction with
dichromate and/or colloid?

Photoflo is a good idea when working with dry pigments. I use Agepon,
the Agfa equivalent, but any surfactant agent should help. Only I use it
in minimal quantities: just a very small drop which is enough to break
the superficial tension of the gum+dichromate mix. Perhaps you are using
too much Photoflo?
