I believe that I can make sodium citrate by neutralizing a citric acid solution with sodium carbonate (specifically the Arm & Hammer I can get at the store, will have to look up exactly which ones). I want to try out some kallitypes this weekend and need a developer. The other option is to mix up some fresh potassium oxalate and give that a spin, but I read here on Apug that Sandy had some trouble with pot ox as a Kallitype developer. Ordering the chems is out of the question as I don't want to order a bunch or pay for the shipping if I can make it at home since this will just be a test. I already have everything else (FO, Silver Nitrate, and the Thiosulfate) I will probably run them all the way through the fixer and final wash before toning them in selenium before I try my hand at Pd toning. Any thoughts?
