[alt-photo] Re: re-acidification of fabriano

[Loris Medici]

Hi Paul, I'd try to use 2% HCl (v/v, for 4 minutes, flipping the paper
halfway...) to see what happens... I used three different batches of
Fabriano Artistico, in past two years and none posed a problem with
cyanotype. (Which is the gold standard test for paper; I haven't seen a
single paper that works well with cyanotype but doesn't with other iron
processes...)

Subject: [alt-photo] re-acidification of fabriano

As a sidebar to my last remarks (see below)...I tried reacidifying my
Fabriano with a stronger solution (5% oxalic acid vs 1%) and let it soak for
a longer period. Paper isbetter but still not hitting on all cylinders.

Has anyone ever had a batch of paper that they couldn't make work? I don't
know what else I could do except more soaking.
