Opacity graph.
Clean start followed by a spike. Notice that there was PM until 85 minutes. While not high opacity, the PM after 50 minutes was
noticeable in the additional power required on the Condar, and possibly heavier than apparent from the opacity. Ie., non-soot like.

Opacity

3.75 lbs of poplar kindling at 15% moisture. The kindling was piled to either side of the crib, with newspaper underneath. The kindling
caught on the left side, but was slow on the right side. It was boosted on the right side with some additional newspaper balls.
