Designer Sho Ota highlights the quality of the wood grain; which character is often neutralised in industrial processing. By chiseling down 12mm from a flat surface and chiseling out the knots, its three-dimensionality and texture are brought out and its unique materiality becomes tangible. A furniture factory and its machines are basically designed to make a flat surface. Underneath the surface, there are hidden secrets of materials related to their origin. By actually revealing this, Ota shows that the grain pattern is not just a graphical pattern but a part of a structure. The structure is originally designed for a tree itself not for us, and we are just borrowing the structure for our daily purpose. Ota cannot control everything and follows the nature of the material, so every object is unique. ‘According to the Grain’ questions the industrial surface and process and revalues the material.
