very dense conifer =710kg/m3

I was cutting firewood, logs and old posts and paling stabs and scrap constructional timber.

Been lying in an open shed stacked cross wise on a double pallet, since the spring.

I reached for a length of 2" by 4" old "studding" type rail.

It was astoundingly heavy, despite being almost rotten and riddled with wood-worm.

But "bone" dry

I cut a random length and set aside.

it measures 264mm by 105mm by 51mm and weighs (pure happenstance) exactly 1.0kg (on kitchen scales)

volume =0.0014137m3

1.0m3/0.0014137m3= 707 times 1.0kg

=707kg/m3

I rounded to 710kg to allow for the decay and wood-worm voids.

The end grain simply looks like conifer to me.

it had been used in construction

what the devil was it:confused1:/is it:confused1:

apart from prime firing.

:blushing::blushing::blushing::blushing:

It could possibly be Oak.

I simply took the "notion" it was conifer, cos in a long straight length, with a clean straight grain.

Plus no tell-tale medularry rays?

i.e. it did not look like any oak I have come across before. but then it is relatively decayed

Could have been the bottle of Armagh cider interfering with my cognative process too btw:lol::lol::lol::lol:

dry dry dry,

its been inside in an airy shed for months

Might run a planer over it, it is rough sawn all round.

see what that brings to light.

No Macro function on my wee Sony digital camera so unlikely to be able to meaningfully photograph.

probably just a heavy bit of pitch pine.

 

a species known as longleaf or slash pine is pinus palustris weighing about 670kg/m3. should be yellowy orange and resinious.

the grain is straight and is one of the heaviest comercial softwoods with the heaviest bits peing sold as picth pine which marries up perfectly with your measurements...

put the blowtorch on it for a few seconds and smell (just my cranky idea, not an official test method)
