I suspect it is bad ferric amm. citrate. I was hoping that there was a
mistake
on my part, but after more tests it looks more and more like the
citrate.

I had already tried two different papers, but as a further test I mixed
a little
of each solution on a clean dry piece of glass. Still a rapid
appearance of blue
when they mixed.
Does anyone know of a method to "purify" ferric ammonium citrate ?
I don't really want to have to buy a new batch (from a different
supplier).
Thank you,
Richard
