Yeah, that's the candle pots we use
The pinecone acts like a giant wick. I usually just use clay plant pots for them.........the tin cans I found got too hot to move if needed while the clay pots were a bit more insulated, if more fragile and not quite as disposable as old haggis tins
I wrap a string around the pine cone and soak it in wax and then wedge it into the wax. Easy light, good light, long burn time......but it's not pitch, iimmc.
Pine splints are just thin sticks of resinous pine. They used to be held in a kind of clip thing, but burnt nubs of them were found on the crannog excavations on Loch Tay, and as far as I know we don't know how the bronze/iron age folks supported them. They can just be shoved into the earth though, just mind your feet
Last ones I tried burnt for about 20 minutes or so. They smell good too
The cross cut log works very well, if it's sited where there's a draught blowing through it; otherwise it does burn but it needs feeding and when it's got enough heat in it, it burns slow and steady, lots of red heat rather than flaming light.
