I'm not being disappointed at all! It's true my comments didn't include
doing nothing other than just air drying the prints. I was just being
negative about putting my prints in bleach and offering an alternative,
because I think in the long run the clorox bleach has done damage
rather than added enhancements.
Though I have never ripped a print in half and put half in peroxide
and dried the other half, I do know the final result will be pretty
much the same. But then a quick peroxide bath does give some instant
gratification by suggesting what the print will look like when it does
dry.

What acid are you referring to? Is this the household bleach that was
mentioned?

The staining happened to all the prints, I wondered if it was because I
had mixed the tannic acid too strong... It did seem to be doing
anything...so I added more!
I went up and checked out the open studio of the alternative class at
UCSC this afternoon. It was the best work done in the class... this
quarter many of the prints were VDB on cyanotype. They did good!
