I must say that I have similar troubles.
Since I made 200 good cyanotypes (old formula with oxalic acid and potassium
dicrhomate added - no bleeding, strong coor, almost no fade) I decided to
try Mike Wares version.
After trying quite a few sort of papers I am bitterly dissapointed. Blue
color dissapears in acidified water very quickly (after a minute almost
gone, color is very pale - nothing from advantages Mike says), picture is
almost impossible to clear, it has yellow stain.
My procedure:
Papers - among others Fabriano Watercolor, Fabriano 4, Fabriano 6. All works
well for Van Dyke Brown print, the best for this proces is Fabriano
Watercolor.
Coating: with sponge brush
Drying: at least 1 hour in dark.
Exposure: 7-10 min on midday sun (6-10 min for my old cyanotypes).
Clearing: water + citric acid
Can anybody tell me, where I made mistake?
