[alt-photo] Re: ANYONE? CYANO TONER WITH COPPER?

[Vedos Projekti]

Hi Bob,

I think in his Cyanotype book Mike Ware mentions nickel sulfate and zinc chloride (?) as chemicals that produce greenish tones, although they are mainly used to make cyanos alkali resistant, if I remember correctly. Can't check right now as I don't have the book at hand...

Anyone?  Was it cupric sulfate or chloride?



DEAR LIST,

            I am going bonkers trying to find a formula for a toner that
changes cyanotypes to a more greenish color.  I seem to recall that it uses
cupric sulfate but I just can’t seem to find the formula.  I have looked in
Christopher James’ Alternative Photo Processes and even Googled it.  Can any
of you send me the formula?

                        CHEERS!
