The pattern (either ‘browning’ or ‘black & white’) seen in damascus barrels is related to the different rate of oxidation of the very low carbon steel (rapidly rusting and black) vs. the corrosion resistant wrought iron (white) when exposed to a mild acidic solution.

Drew I appreciate and have read all I’ve found on your posts here, on other forums, and anything you’ve provided links for regarding Damascus. I completely understand your response here. Thank you.
