| Species information for this product: |
-
The sapwood varies from straw to pale yellow, and is not distinct from the heartwood, which is cream to pale brown with ripple marks appearing.
-
The grain is generally straight but can be shallowly interlocked producing some beautifully figured wood with a moderately medium to coarse texture. Also the attractive figure on tangential face and large ray fleck on the radial face are prominent features.
-
Logs are reported to be vulnerable to blue-stain, termite, and pinhole borer attack if they are not promptly removed from the forest after felling.
-
Seasoning is very slow, however the wood can be kiln-dried from the green condition, but there may be some degrade in the form of end-splitting.
-
Turning and moulding operations are easy and give an excellent finish. Sawing and planning can be difficult with low speed machinery. Penetration and retention of preservatives in both sapwood and heartwood are reported to be adequate.
