Specific gravity of balsa wood
WebRot Resistance: Rated as non-durable; poor insect resistance and liable to fungal staining and discoloration if not dried promptly. Workability: Generally easy to work, though the interlocked grain can cause some rough surfaces in some machining operations. Carves, stains, glues, and finishes well. WebA good indicator of a wood’s strength is its density — the weight for a given volume. This is measured by its specific gravity — the weight of a volume of wood divided by the weight of the same volume of water. Generally, the higher the ratio, the denser and stronger the wood.
