Re: Dark reaction
Agreed, Loris and Judy,
I always coat in room light and my students do as well under
fluorescents. But I never let the paper dry out in room light or
whatnot. Mine goes in a closet until use.

PS Yes Judy, memory serves you-- books of a couple decades ago said to
coat under bug light. When I first started gum printing I always
coated in my basement with a yellow bug light. I feel much liberated.

I once did a test placing a plastic fork over the dry paper (to check
unexposed vs exposed) and observed a definitive fogging (normal
yellowish
color under fork, greenish/bluish everywhere else) of trad.
cyanotype (the
slowest UV sensitive process I know) in about 30-40 minutes. So,
fogging is
definitely there, always, but inconclusive as long as you follow
rules (a.)
and (b.) above...

I have however come across warnings against fluorescents in "the
literature," but wonder if the warners ever tried it. As I've probably
mentioned, when I was teaching "non-silver," the classroom (a
repurposed
chem lab) was lit by several banks of fluorescent lights set in a
fairly low
ceiling.
But I gather that some folks really do coat by safelight -- and, if
memory
serves, some how-to sources advise that. (Is that possible? YIKES!)
