RE: Cyanotype Eraser Maybe Reducer

Can you put the paper in acid environment and see if the cyanotype comes
back (maybe less dense)?

Subject: Cyanotype Eraser Maybe Reducer

So I'm putting test drops of my supposed ferric oxalate (another story
not finished yet) emulsion on the back of some classic cyanotype test
strips to save on paper. After baking the strip I throw it on the bottom
of my darkroom sink and splash some "kallitype" developer on the ferric
oxalate spot to see what it does. I end up going up for dinner. When I
come back the thing that strikes me (other than I've still failed to
make a reliable ferric oxalate) is that the kallitype develper has
erased almost all of the cyanotype from the other side. Erased or
bleached, it's gone no more cyanotype. 50g. Borax with 40g. Rochelle
Salt in 1litre of water. What's going on here?
