Bleaching Azo : LUSENET : Large format photography : One Thread

I am going to try my hand at contact printing 5x7 negatives on Azo paper and have read most of other questions regarding light source, etc. In searching the responses I was unable to find any info on bleaching. I know almost any paper can be bleached, but how does Azo respond as far as time, staining, etc.? I'd appreciate any help.

Azo responds well to bleaching as well as toning. I find I need to mix the ferricyanide bleaching solution a bit weaker than with some other papers. Don't get in a hurry or you will crinkle the paper when trying to pull it out, rinse or put into the next bath. It works well with overall bleaching to clear whites a bit or with local bleaching.
