cyanotype problems
You should not be having all those problems with cyanotype. In my
opinion, it is one of the easiest alternative processes, if not the
easiest.
Judy is absolutly right. Those exposures are just too long. We need
to know (1) the nature of your light source and (2) what you are
using as a negative.
I do niot believe that the Ware cyanotype process is any more
difficult than the classic method. It is perhaps more difficult
to mix the sensitizer.
I have printed cyanotype on all kinds of paper and natural fiber
cloth with good results. Unless you are using a buffered paper,
the paper should not be the problem.
Suggest that you get a step tablet, mix up some classic cyanotype
sensitizer and print the step. This will be a clue as to the
type of negatives you need.
In the meantime:
What are you using as a light source and how far away from the source
is the print frame?
If you were to use the same negatives to make a silver/gel print,
what would be the exposure and what contrast filter would you use?
What is the pH of your wash (tap) water?
