PHOTOGRAPHERS' FORMULARY JD-4 KIT BLEACH

35 g  Copper Sulfate
5 g Sodium Bisulfate
100 g  Potassium Bromide
One litre water

Bleaching time: One and a half times the time it takes to clear.

Temperature:  20C            Agitation:  Intermittent

More or less the same as the original Jeff Blyth's original Copper Sulfate Bleach, again subbing a dry powder to save on hazardous shipping charges of liquid acetic acid.

Shelf life: Pleasant blue-green color when mixed, dirty green when exhausted.  Not prone to oxidation like PBQ.
