Richard. If memory serves me correctly (and at my age, if often doesn't) Potassium Ferricyanide (I don't know the difference between ferricyanide and cyanide) was used in tintype photography as well as in some print toners. of course tintype photography was late 19th to very early 20th Century. think the most used was potassium ferricyanide, a salt of potassium (duh!) and a complex of cyanide and ferric ions ([Fe(CN)6]-3). Ferricyanide in itself is not that dangerous if handled properly, but can liberate cyanide gas (HCN) under certain conditions. The latter is highly toxic.
