Mark,
Interesting problem. Of course cyanotype comes to mind but I think you need
to start by finding an iron compound that will interact with oak. When you
say that iron will stain oak black, does that mean metallic iron or some
iron coumpound? If it is metallic iron, then I might suggest the following.
It is possible to obtain very fine iron filings at a chemical supply house.
You could use these to replace the pigment in the gum bichromate printing
process; however, you might want to test first to see what the bicromate
will do to the metallic iron.
If it is an iron compound then, again it could be used to replace the
pigment in the gum process.
Just for the heck of it you might try putting cyanotype on an oak board to
see what happens.
