From: Iron acetate solution prepared from steel wool and vinegar for ebonizing wood
Cherry (left) and red oak (center) veneer treated with iron acetate solution, the product of aged Rhodes steel wool–DW vinegar reaction, and viewed edge on along the grain (vertical axis) by optical microscopy. The scale of the photos and the average thickness of the veneer was 600 µm. The ebonized wood layer is the slightly darker band on the left side, and its thickness was estimated by ruler measurement of the photo. The third photo (right) is of the holder used to secure the veneer edge perpendicular to the optical path of the microscope. The edge of the wood (and top of the holder) was sanded to 4000 grit prior to microscopy
