OLIVO! NO!NO! NEVER airbrush dichromates -- unless you have hood &
mask. Chrome is the most allergenic substance known to humankind, not
to mention poisonous. (Only turpentine, and in my experience cat hair,
come anywhere near it.) Even if you're not allergic now EVERYONE will
in time become allergic to dichromate -- not to mention all the people
breathing in your vicinity.
Incidentally, if you want fine detail in a gum print, the coat should
not be all that thick and sloshy, but rather buffed or burnished.
Flow it on first with a foam
brush, then smooth & buff with dry wide "hake" type brush, but a cheap one,
as noted in my post to Adam. Made in China (probably by prison labor,
awful thought) they cost about 3 to 6 dollars at NYCentralArtists Materials
in New York.
The metal ferrule doesn't
matter here because emulsion only touches the very tip, though you'll
want to douse the brush in a tub of water & pull out loose hairs a few
times before using. (Optional also to slide card into bristles the long way
& cut half of them off, like platinum printers used to do to save
It may or may not help to coat the area around the
base of the hairs with something like airplane glue to hold them tight
-- I do it but the help may be mainly psychological.
