The first material is BAST, which is a type of fiber obtained from the inner bark of certain trees, such as linden and lime. It is often used in the production of rope, twine, and other cordage. The second material is FIREWOOD, which is wood that has been cut and dried for use as fuel. FIREWOOD is often used in fireplaces, wood stoves, and outdoor fire pits.
