  Betreff: Ammonium iron III citrate BROWN

  I am presently taking up printing cyanotypes (again) and I ordered some Ammonium iron III citrate, which was delivered in the BROWN variety. It is hard to find some information on this variety, but my main question at this stage is:

  To make sensitizing solution A (in the green variety) 25 g is needed to make up to 100 cc of solution A. Would one need the same quantity for the brown variety solution??
