Hi Folks Dr Mike Ware Cyanotype process calls for Ammonium Iron Oxalate 30g, Potassium Ferriycyanide 10g, Ammonium Dichromate (25%) 0.5ml and distilled water to make 1ltr. My problem is that Iron Oxalate is illegal in the UK being on a poisons list and I have tried a couple of places in the US who have said they are not allowed to export. Is there a substitute or somewhere that would ship to the UK? All the best, Carl. ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
