Iron staining, or ebonizing, generally uses a reaction between iron oxide and the natural tannins in wood to create a natural-looking black that is actually created in the fibers of the wood rather than a stain sitting on top. This is why it is so durable. It is integral, not superficial. I have also found it to be very light-catching.
