Several list members have requested the following formula so here it is:

This formula results in prints with no bleeding and
very white highlights.

Solution A: Ferric Ammonium Citrate 68 gm.
Oxalic Acid 1.3 gm.
Water to make 250 cc.

Solution B: Potassium Ferricyanide 23 gm.
Oxalic Acid 1.3 gm.
Ammonium Dichromate 0.5 gm.
Water to make 250 cc.

Mix equal parts of solutions A and B just
before use. Store all solutions in brown
bottles. Distilled water preferred.

If anyone trys this formula, I would appreciate hearing how it works
for you.
