Finishing notes. To harden, heat until a magnet will not stick and the color is even, then quench tip-first in a light oil without swirling. Temper at 350°F for one hour for a light straw color. Etch with ferric chloride and distilled water, neutralize with baking soda and warm water, and dry quickly to prevent flash rusting. Finish with a light oil or Renaissance Wax. Use caution when working with acid. |
