Burnt wood, also known as charred wood, is wood that has been partially burned, resulting in a blackened surface. This process can occur naturally through wildfires or intentionally through techniques like shou sugi ban, a Japanese method of preserving wood. The charred layer helps protect the wood from pests, decay, and weathering. In addition to its protective qualities, burnt wood is often used for aesthetic purposes in construction and design. The unique texture and color can enhance the visual appeal of furniture, siding, and other wooden structures. Its popularity has grown in modern architecture and interior design for its rustic charm.
