Heartwood Color Yellow Orange Brown Red White Purple Yellow to golden-yellow to orange Reddish brown Pale brown Brown White to cream Freshly-Cut heartwood is yellow but darkens to pale yellowish-or reddish-brown upon exposure. Sapwood Color White Yellow Brown Red White to yellow Wide sapwood Paler than heartwood Color not distinct from heartwood Grain Straight Interlocked Crossed Spiral Even Figure Weak (figure) Straight Interlocked Spiral Weak figure Texture Fine Uniform Even or uniform Very fine Fine Very fine to fine Luster Medium High Lustrous Pronounced Natural Durability Moderately durable Non-durable Durable Perishable Susceptible to insect attack Non-resistant to powder post beetles Resistant to powder post beetles Moderately durable Non durable Durable Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Resistant to attack from powder post (Lyctid & Bostrychid) beetles Perishable Resistance to decay varies from fair to poor. The timber has moderate resistance to the harmfuls effects of the weather Weathering Good Odor No specific smell or taste Light-Induced Color Change Darker Kiln Schedules Kiln Drying Rate (in days) is fairly rapid Drying (speed) is fast Dry at a slow speed Drying Defects Checking Splitting Distortion Slight surface checking Slight end splitting Slight twist/warp Slight checking and cracking No twisting or warping No end splitting Expect splits Ease of Drying Fairly Easy Rapidly Slowly Easy Kiln Drying Rate Drying rate is fairly rapid to fast Naturally dries quickly Naturally dries slowly Fairly rapid (11-17 days for boards under 32 mm, to 31-51 days for boards greater than 63 mm) Tree Identification Bole/stem form is buttressed Bole/stem form is fluted Bole/stem form is straight Tree Size Trunk diameter is 100-150 cm Tree height is 30-40 m Tree height is 20-30 m Bole length is 20-30 m Bole length is 10-20 m Tree height is 10-20 m Tree height is 0-10 m Bole length is 0-10 m Tree height is 40-50 m Bark width is 10-15 mm Trunk diameter is 150-200 cm Comments Acid resistant General finishing qualities are rated as good Useful for manufacturing saunas, laboratory bench tops, and other applications where acid-resistance is needed Carving Fair to Good Results Good results Cutting Resistance Easy to saw Cutting Resistance with dry wood is easy Cutting Resistance with green wood is easy Gluing Fairly Easy to Very Easy Easy to glue Mortising Fairly Easy to Very Easy Very Good to Excellent Results Fair to Good Results Easy to mortise Finishes well Moulding Fairly Easy to Very Easy Fair to Good Results Easy to mould The wood can be moulded or shaped with minimum effort.
