[Marbling] "aluming" paper; indigo
- Overall, I found indigo, though it stayed on for me to be very "rubby" when
dry, requiring a fixative. I only make paints now from pigments that leave
minimal if any rub. Bookbinders will hate you for this! Indigo always
offset onto the opposing sheet, got all over their hands and smeared.
As for alum.....I was never taught to marble so did it my own way. I hated
stopping to alum when I wanted to marble, so I tried aluming ahead....days
ahead. The trick is they must be totally dry before stacking, I mean the
room they are stored in must bee at least under 55% humidity....preferably
50% or less. I have stored them for years and they still work. I find they
work better than damp papers for me.
With the current buffer problem, my Classic Linen works better dry than
freshly alumed. I am blasting the theory here on alum needing to be freshly
done and damp....have been doing it this way for nearly 26 years. The
secret is keeping the paper dry. I run a dehumidifier all summer. Winter,
I wonder......if both sides of the paper are equally
buffered.....ah....another experiment for next week. And I will try to wash
some down first. Maybe a bucket and separate sponge with plain water
first.....or wet and squeegee off. However, since I alum sometime 250
sheets in a session I may just lose my mind over this.
