[alt-photo] Re: European distributor for Aerosil (fumed silica dioxide)

[Loris Medici]

Yes, I saw it thanks. I'm doing as described by Robert Hall @ APUG - I
couldn't find high density foam rollers here.. I think the streaking
can be eliminated by increasing the coating soln. volume by 30 to
maybe 50%, and by making sure to *not over-brush*. (Particularly
quirky for trad. cyanotype; since it doesn't want to get IN the paper
by nature!) I'm sure I'm going to get used to it after some
experimentation...

Will size FA, Masa, Yupo and aluminum with gelatin+silica
fume+formalin mixture later.. (Masa, Yupo and aluminum were
particularly problematic - too slick! - with gum for me.) But I just
want to nail down the optimum parameters for iron / iron-silver
processes first... (I'm going to try coating with a glass rod too...)

Will share the results along with non-treated control prints later.

Regards,
Loris.
