I would have thought Prussian Blue would be oil based and not real good for wood use.
Many years ago I worked at an engraving shop building 3-d type dies.We used bluing of several types.
Prussian blue was most excellent for use on machine handles, back of bathroom door knobs and under lunch box handles. Just imagine where the blue would rub off if you did not know you had it on your hands.
Of course someone told me about this, I really didn't participate.
