I'm intersted in locating a supplier for ferric citrate as i'm intersted in using Liam lawless's contrast control formula for VDB as mentioned in Post-factory no.8...that article mentioned www.tri-esssciences.com as a source but i just got email from them saying they dont have it...artcraftchemicals/bostick/photoformulary dont have it either..any ideas?

TIA
