Shou Sugi Ban is a simple, beautiful wood burning technique designed to naturally preserved wood and historically used in Japan for wood siding.
Wood begins raw, as with the in-progress rings below:
Then you apply flame with a torch, clean and sand the wood as desired, and treat it with linseed oil. I like to use lacquer, sometimes, too, to seal the ring and reduce the lovely but agressive burnt-wood smell.
Here's a before-and-after:
And the final product:
I like using Shou Sugi Ban because it's a natural finish, and one that mimics the self-preservation of a tree in a forest fire: it's the last line of defense, and the particular way the wood burns creates a barrier between the flames and green, live wood.
It's this kind of natural strength I like to honor in my work, through my materials and processing, whenever I can.
