k
Bostick and Sullivan is a good source (maybe the only source) for ferric
oxalate, and it is not that expensive relative to the other compounds
needed for the process. For preparation in your home lab (I am also a
chemist) Check the references in Luis Nadeau's "History and Practice of
Platinum Printing" or Dick Sullivans "Lab Notes".
BTW, potassium oxalate is soluble in three parts water, and the ferric
oxalate we use in platinum printing is a saturated solution at 27%
