Re: cyanotype with gum

Anne,
I agree with Dave. in fact, with the gum on top it gets richer. I figured
it was the acid in the gum and/or the protective layer that helped, as
cyanotype loves acid and doesn't like alkalinity. Around the borders where
the cyanotype is nekked outside the gum that is coated on top there is a
slight fading due to extended wash periods from developing the layers of
gum, though, but where the gum is covering the cyanotype no fading occurs.
Or, at least, that is my experience with hundreds of gum over
cyanotypes...(you never can be too sure on this list).
