If youre needing kindling it may well be that your logs are too moist.

snip loads of stuff unrelated to the question

The wood is very dry and in big chunks.

If I stuff one or two fire lighters in there than it usually goes pretty
quickly.
However I am experimenting on lighting without using fire lighters.

I have noted that big solid blocks of wood are reluctant to burn
straight off (applying a weed burner as a heat source) but that if there
are a few small bits of kindling the whole thing takes off with a
vengeance.

I am also considering as noted above that I think it may be more
effective to start with some small pieces to get a good set of embers
going then put the larger pieces on later.

Wood only burns at the surface, so chunky logs burn for a long time but
all that wood in the middle doesn't contribute to the fire for some
considerable time.

So small pieces to start are required.

I have noted that even a few small bits of wood - mere splinters - are
often enough to get the larger bits of wood blazing away merrily. I
assume some kind of wicking effect.

Yep, just proved that again.

A few slivers of wood between two large logs and the whole thing bursts
into flame.

Just the two logs and an air gap and it glows but doesn't burn.

So kindling it is.


when cutting up trees always cut up a few smaller branches and stack
them separately for this precise use
