Other Uses

The heartwood is creamy white to pale yellow, darkening to golden yellow upon exposure to light; it is indistinctly demarcated from the 5 - 6cm wide band of sapwood. The grain is straight to interlocked; texture fine and even; the wood distinctly lustrous, with a silky shine; quartersawn surfaces often have an attractive mottled figure. The wood is medium weight; soft; it is not durable, being susceptible to fungal, dry-wood borer, termite and marine borer attacks. With some care, it air dries fairly easily and rapidly, but there is a serious risk of distortion and slight risk of checking. The wood saws and works well with ordinary equipment and with only slight dulling effects on saw teeth and cutting edges; tearing may occur in planing because of the presence of interlocked grain; it can be polished to an excellent finish; splitting is common during nailing and screwing, and pre-boring is recommended; gluing, painting and varnishing properties are all good, but the bending properties are poor. Sliced veneer of excellent quality can be produced, but the logs are often too irregular to produce good results in peeling[
