Shou sugi ban
While shou sugi ban (焼杉板) originated in Japan in the 18th century primarily as way to treat cedar siding to make it weatherproof, the technique—which involves charring a wood surface to render it a deep charcoal-black—has caught on recently as a treatment for contemporary exteriors and indoor furnishings alike. You can even find variations elevated to fine art, as in the work of the artist Maarten Baas. The gravitas imparted by the process and finished result (called yakisugi) are undeniable, a blackening of the wood that reveals clean, distinct lines and an inherent textural beauty. You might not be the proud owner of a blowtorch (yet), but any intrepid DIYer can absolutely accomplish the technique at home to give an existing piece of wood furniture a new look.
