Dear Tom

I would be interested if your experiments can add to the findings in 
this paper.

The electrical properties change and may correlate well with other 
properties. Resistance/conductivity is at least is one property that is 
fairly trivial to measure in char from 1/2 inch+ thick wood sticks. So 
even if your using pellets insert a stick.

Stick with it :)

I have measured the temperature of formation of the charcoal as 500-700 C, depending on how much air is inducted or blown in, but the measurement may have been biased by the flame.  In any case, this is the charcoal produced in WoodGas stoves or PyroPiles of wood by burning off the volatile cellulose gas during which the lignin becomes the harder to burn charcoal.
