Sapwood Color White Clearly differentiated from the heartwood Initially whitish, but it turns to a pale reddish brown color upon drying. It is about 0.8 to 2.4 inches (2 to 6 cm) wide Grain Figure Crossed Crossed Distinctly crossed in broad bands. Texture Medium Coarse Natural Durability Resistant to termites Moderately resistant to decay Heartwood susceptible to attack by decay fungi and insects. Heartwood is rarely attacked by beetles Odor No specific smell or taste Drying Defects Checking is slight, but the wood has a tendency to warp if not carefully seasoned Ease of Drying Thick Stock Requires Care Fairly Easy Little degrade if dried properly Dries well under good controlled conditions Comments Kamatog is described as a moderately heavy and moderately hard timber.
