Charred wood, also known as burnt wood or shou sugi ban, is wood that has been intentionally burned to create a protective layer of charcoal on its surface. This process enhances the wood's durability, making it more resistant to weather, insects, and decay. The charred layer also gives the wood a unique, textured appearance that can be aesthetically pleasing. In addition to its practical benefits, charred wood is often used in construction and design for its distinctive look. It can be found in various applications, including siding, furniture, and decorative elements. The technique is gaining popularity for its sustainability, as it can extend the life of wood products without the use of harmful chemicals.
