Not much to say except it is one half of what you need for coating paper for cyanotypes using the classical formulation. Packaged well and always works.

Use it for bleaching bw prints. I've only done teats strips so far but it works. Dissolves yellow into water. Add KBr as a restrainer

if I get 100 grams Potassium Ferricyanide should I get 250 grams Ferric Ammonium Citrate to get proper soulution for cyanotype prints ?
This would be a proper mixture for cyanotype prints.

question
I have several fibre prints which are printed about half to one stop darker than I would like, can I use potassium ferricyanide as bleach to brighten them up a bit? What is the best dilution ratio? Is it still okay to selenium tone the prints after bleaching?
It is better to use a Farmer reducer for a whole print bleaching. And yes after the bleaching prints can be toned in celenium.
