Description

The wood taken from a Burretiodendron hsienmu tree is very hard, tough and durable. It has grain and would not suffer from termite infestation if buried in the ground for a long period of time. Because of its great properties, ethnic minorities on the high rocky area (mainly the Tay people and Nung people) use the wood to make the columns, floors, etc. of the stilt house. The boards are so flexible that walking on them does not produce the slightest noise. Another popular item to make from Burretiodendron hsienmu wood are cutting boards.

The downside of furniture made from this species' wood is that the influence of moisture and water can easily bend, wrap or even break thin boards.

The duramen has a uniform dark brown with fine, but easily distinguishable grains and delicate flower pattern on the surface of the steel as the Japanese sword when shaved (not all trees have this property). Rain water can only fade the outermost layer of the wood. The sapwood is lighter in color, softer and weightless than the heartwood. It is prized as a material to make the altar, furniture, etc.

gollark: There actually are worries about development of this stuff slowing down.
gollark: <@!336962240848855040> As far as I know 3nm does not actually exist yet, and there are a bunch of possible sizes you could use.
gollark: > The 22 nm node may be the first time where the gate length is not necessarily smaller than the technology node designation. For example, a 25 nm gate length would be typical for the 22 nm node.
gollark: As far as I know it *used* to actually be a measure of something, but they hit issues around... 22nm or something, don't really know... and despite said measure not changing very much the processes kept getting better, so they just reduced them.
gollark: I mean, generally if the number goes down the density of the transistors goes up, but it's not an actual measurement of anything.
