cyanotype question

I am asked offlist to recommend paper for cyanotype, but thought I'd
answer generally, in case others need an opportunity to disagree...

Basically, any decent paper with a rag content is likely to be excellent.
We just did cyanotype in class, & one of the best was "my sister's typing
paper from the office," which had 25% cotton.

Your major decision is do you want texture or smooth. I don't know why
people like that texture to mess up their negatives,"arty" I guess. But do
they listen to me? Of course not.

And needless to say the paper should be able to take some soaking in
water. (Lana is one of those has no wet strength.) But the wonderful thing
about cyanotype is how many quite cheap papers are excellent.... no-name
artists drawing bristol, bristol plate, Strathmore 400 sketch (in a pad),
an Aquabee sketch pad, 45 cent "recycled" drawing paper from the school
store (showed thingies when wet, but dried clear), even
"visualising" paper from pad were among successes.

For more cachet (and probably better archivality) try Stonehenge, Fabriano
Artistico, any strathmore drawing (500 series excellent), cranes
platinotype, arches platine (assuming you have a trust fund -- it's much
more expensive than necessary), Somerset Velvet, + lots of Arches. And
needless to say Buxton if you just happen to have a batch hanging
around. This very day I bought some Zerkal book and Somerset book extra
heavy which I like for gum, and I bet they'd be good for cyanotype, too.
Simili japon, which was one of the favorites for platinum looks like it
would be excellent for cyanotype if you've got some of that around either,
too.

In fact I've only seen one "brand name" paper not good for cyanotype &
that's Rives BFK. (Do I hear it from Bob S?) No-name papers that will not
print reveal themselves by making a brownish, rather than a deep blue. I
suspect presence of some alkali or alum. (Cyanotype doesn't like alkali.
Avoid anything "buffered." )

Be advised, however,that there is a great difference in "speed" among
cyanotype papers. Each student had a different paper, more or less, and
for their first prints each for whatever reason began with around 8 or 10
minutes -- the step tablets printed anywhere from #3 to 16! Yes the 16
steps were on ...... oops I left that folder in school... I'll get back to
you next Monday.

Meanwhile, notice that you can match the "contrast" of the paper to
your negative.If negative is on the flat side, use a paper that prints
fewer steps. etc.
