If my memory again serves me well, to drive out the tars and oils from wood requires heating to several hundred degrees. When done in an oxygen free atmosphere the end result is torified wood, which does not re-absorb moisture.

@derek-m, forget memory, you're already past my original knowledge.

I followed up what you mentioned and you're quite right. It seems the process drives off volatiles and reduces the calorific content by about 10% whilst producing a hydrophobic and stable fuel source. Or dimensionally stable material for guitars, but that's another story....
