Dichromate Print Intensifier
(Source : Amateur Photographer - 1993)

Solution A

Water 100ml
Potassium Dichromate 5g

Solution B

Hydrochloric Acid 10%

Potassium Dichromate is toxic.

Working Solution

1 part A + 1 part B + 6 parts Water

Use immediately. Discard after use or when bleaching effect slows down too much.

Fully bleach print in working solution, then re-develop in print dev. Does not seem to have much effect on print, but seems to affect subsequent toning, e.g. splits toning, particularly on RC. Try only partial bleaching for spilt toning. Try adding more water to working solution to slow down the speed of the bleach.
