Emily,
Some tap water is slightly alkaline, so a long soak in it would bleach out
your cyanotype, which doesn't like alkaline, prefers slightly acid. So you
might put just a bit of acid in the soaking water, perhaps a few drops of
HCL... better yet of course would be to test the water. Someone on this
list will know "normal" water pH -- probably about 7 ?? Have you got pH
testing papers?
However, cyanotype may have the effect of tanning the image area, which
might or might not interfere with accepting the intaglio... Hope
you'll reveal how it goes...
Judy
