Very nice- holds the cut well for 404 and that wood its in, very hard

 

[davidwyby]

Euc has black crystals in it

 

[pbillyi69]

do you find them often?

 

[davidwyby]

full of it, old dried up sap

 

[justoldsaws]

I find it often, especially in River redgum, looks like pockets of black glass, if the timber is cut green the sap looks like black molasses and is quite sticky.

 

[pbillyi69]

does it burn good? could it be used as fire starter

That must be quite abrasive, no?!
Very interesting.

Burning turkey oak days on end tends to accumulate a stone like substance of blueish color in the burn chamber, the lesser You poke the fire the bigger and harder these stones get.
My dad tried after burning them with a propane torch, they don't burn nor change consistency.

I never encountered unsplit bone dry turkey oak, but I imagine it might create similar crystalized inclusions.
Which is why I don't even try to cover fresh split turkey oak. I let the rain wash out at least some of the sap.

@rogue60 @deye223 @Trains

this guy from down there has been making his own hexa and says it holds up well.

I know nothing but have heard metal will turn walnut blue. Could it be super fine metal particles in the wood causing these phenomena that I’ve never seen?

The biggest I've pulled out of the stove burn chamber was like the size of half a mans fist!
Never found any of those "chunks" in the cast iron fireplace.
Maybe it is a "slow burn" thing where a heat induced oxygen deprived chemical reaction occurs?
Same firewood in stove and fireplace, just bigger chunks for the latter!

 

[Wilhelm]

So, 4AM and I just fed the stove and fireplace.
Pulled this little piece out of the stove, it wasn't there 5 hours ago when I filled the burn chamber with turkey oak and completely choked down air inlet.

 

[jakethesnake]

What is it!!!!?

 

[Wilhelm]

What is it!!!!?

I don't know, maybe some sort of silica the tree absorbed during its lifetime?!
My firewood logs tend to be large in diameter, thus making the tree having had old age and decades to ingest who knows what.

That stuff can not be found burning ash and beech firewood which I have too.

It's just dry sap ya get pockets of sap in some Aussie timber its not uncommon to find.
Depending on the species of tree it's colour ranges from dark almost black to golden yellow.
It dries out hard but doesn't seem to dull chains. I've tasted it fresh yeah yuk it's very bitter lol

Here's a pic of Bloodwood ya can see how it got its name.
I've got one nice slab of Bloodwood I cut years ago its hard to get clean timber out of that isn't full of pockets of sap.

 

[Wilhelm]

Turkey oak tends to "bleed black sap" within itself fully alive.
I believe my burn chamber findings are from burning firewood originating from such sap rich logs.

That Bloodwood is something special though!

If it was me, before I ruin a bunch of chains and saws, I would get a few gallons of diesel and several matches.

I’m doing pretty good selling it as firewood.
