A ___ is bark on the edge of lumber or the surface from which the bark has fallen.

• A. Bark
• B. Wane
• C. Rind
• D. Grain

Answer: (B)

Wane describes bark on the edge of a board or the surface where bark has fallen away. In milling, this term is used for the edge condition where wood is missing or the bark remains attached, creating an irregular border along the board. It’s a common lumber defect that affects appearance, planing, and joinery, because the edge isn’t clean wood all the way to the edge. This is different from bark itself, which is the outer protective layer of the tree, rind which isn’t a standard lumber term for edge conditions, and grain which refers to the direction and pattern of the wood fibers rather than bark presence.
