I am trying to find and buy about 100 grams of Ferric Citrate within overnight shipping distance of Cleveland, OH USA.

On page 221 of Christopher James’, “Alternative Photographic Processes”, 2nd edition, James suggests substituting Ferric Citrate in equal parts for the standard Ferric Ammonium Citrate in part A to increase contrast.

It is not offered on either Bostick & Sullivan or Photographer’s Formulary websites. It does appear to be offered in vitamin capsules of 25 milligrams (fun to tear apart and accumulate 100 grams) or at huge chemical companies (in kilos) if I submit a request for quotation. What I need to figure out is how and where to buy about 100 grams of Ferric Citrate and get it here in a short period of time.

Thank you,

John Powers
