Bleach for lith re-development

I wanted to try this over the holidays. Anyone out there with some recommendations of the makeup of the bleach (I thought CuSO4 had something to do with it!) and any tips for how to make the original print (e.g. darker or contrastier or ???)

Thanks -- Mark

It ideally needs to be re-halogenating with chloride or bromide.

80g/l Potassium Ferricyanide, 20g/L Potassium Bromide is my traditional bleach for most toners I work with. It can be be re-used. I actually use this old C-22 bleach for when I am short of the Kodak C-41/E6 commercial bleaches for c-41. In that application I replenish it 45m/l per 80 sq in, and keep the overflow for one shot b&w print bleaching. Dispose of this at HHW. I leave it out to dehydrate somewhat in the garage once it is too slow to reduce it's volume before spatula'ing it up and turning it in, in a well labelled bottle.
