THIS MIRROR WENT INTO THE MAIN DINING ROOM AT THE WILLOW'S INN ON LUMMI ISLAND. SHOU SUGI BAN (OR YAKISUGI) IS AN ANCIENT JAPANESE TECHNIQUE THAT I'VE BEEN PLAYING WITH THAT PRESERVES WOOD BY CHARRING IT. TRADITIONALLY, SUGI (JAPANESE CYPRUS) WAS USED FOR EXTERIOR SIDING. THE PROCESS INVOLVES CHARRING THE WOOD, CLEANING IT WITH A METAL BRUSH, AND FINISHING IT WITH A NATURAL OIL.
I find that the method works well on our local douglas fir. The soft summer growth of the fir charrs more quickly. After scrubbing the surface with a wire brush, you're left with a very tactile and weathered surface.
