Disregarding? Wasting time and energy? Did I said something to hurt your feelings???
What, you think you have discovered a way to put carbon in the steel without heating it? This "super duper secret horn flattening method" is as old as the human desire to flatten horn, and it's widely known around the world...
btw, as a data point for your experiments, horn's melting point is at 350F, and nowadays, horn is heated in oil bath and flattened in a press.
