Another approach as described recently in TNPP is to mix equal parts of
developer (potassium oxalate and "cold bath" both work well) with
glycerine and then use a small amount of this as a one-shot to develop a
pure platinum or Pt/Pd print by brushing in on--10cc or so for an 8x10.
This also allows use of ammonium dichromate in the one-shot developer
for contrast control. I've no idea how it might apply to gold-colloid
printing though.---Carl
