Monumental Wooden Chair, Asian Work, circa 1970
This monumental wooden chair imposes by its unusual size. The burned wood technique used by the designer is a very old technique that gives the wood special properties and gives it a rustic appearance. Its monumentality is lightened by the openings created in the back of the chair. Although the seat and legs of the monumental wooden chair have been carved, the back of the chair seems to be in one piece, a single wooden board cut in a very natural way.
The wood-burning technique used on this monumental wooden chair, also called shou-sugi-ban technique, is of Japanese origin. The carbonization of the surface of the wooden blades allows an effective natural protection. Indeed, the carbonized surface allows the creation of a protection against UV rays, mainly at the origin of premature ageing of wood. In addition, this carbonized film protects against bad weather and wood-eating insects.
Traditionally, this technique was only used on cedar (Sugi) but now all pine woods lend themselves to this method. It takes about ten minutes per board to burn. Then a brush is used to remove the coal residue created by combustion. The boards are then sprinkled with water and dried. Linseed oil can also be coated to perfect the whole and make the material hydrophobic.
