Hey BizHB
I have had good results with cherry and oak in simulating an ebonized
surface by a chemical mehod. Soak some pieces of rusty iron, old
nails or the like, in vinegar for a few days and paint the (filtered)
solution on to the wood. You will want to experiment with dilution so
as to contol the effect - it gets real black real fast if you are not
careful . The dissolved iron salts interect with the tannin in the
wood to turn it black.
