I ebonized some oak with India ink, and it was not all I expected.
Once dry I rubbed the pieces down and quite a bit of the ink balled up and came away from the wood.

A second coat and it might be fine, but I figured I'd ask as to whether in your experience some brands of ink work better than others for this.
I used Blick Art Supplies own brand ink. It uses shellac as the binder. Do this all use shellac?

thanks, Mark
