Duramen
Duramen refers to the inner, harder, and more durable wood found in the center of a tree trunk or branch. It is formed as the tree matures and consists of densely packed cells that provide structural support and strength to the tree. Duramen is typically darker in color than the outer layers of wood, known as sapwood, and is highly resistant to decay and insect damage. It is commonly used in furniture making, construction, and other woodworking applications due to its strength and durability.
