OK, the wood actually, when split, is red and green. I suspect the green is spalting or something and the red is natural. What kind of wood is it? I have my suspicion, but the log was bark free, dry, and lying just off the ground. It is tough to split but burns readily in the airtight stove, so is apparently 12% moisture or thereabouts. Notice the chatoyancy of some spit sections. The background logs with bark on from a different tree, so do not judge the split sample by them.
