DEAR JUDY,
On p. 38 of WJPFP #7 you have a paragraph "...from Tony McLean on toning
cyanotype". It describes using either Nickel Sulfate or Nitrate to make the
Cyanos "alkaline resistant" though what caught my attention was the
statement that this "...will produce a color shift toward turquoise..."
Well, I have obtained some Nickel Sulfate and would like to have a
suggestion as to the concentration of the solution in g/Liter or %. You
cite it as being from "the list". Is Tony out there? Or did he tell you the
concentration?
CHEERS!
BOB
