Restoring Burnt Steel

It is said that burnt steel may be restored by making a powder composed of 8 oz. sal-ammoniac, 3 oz. prussiate of potash, 3 oz. borax, 1 1/2 lbs. resin, 2 oz. blue clay, 1/2 pint alcohol, and 1/2 pint of water. These ingredients are to simmer over a fire until dried to a powder; the burnt steel may then be reheated, dipped in the powder, and hammered. See TEMPERING.
