Wood Science 101 (22) - Which Log or Pellet is Right for Your Stove?

Last post I alluded to my work talking to folks about firewood and pellets at the Pennsylvania Farm show. I thought today I would share those ideas with the rest of you.

1. Firewood

People love to talk firewood, especially if they burn it for heat. This year, our display included about a dozen different sticks of firewood. But these sticks were special. All were of different species, and sizes...but they all had the same mass, or what we call in wood circles, dry weight.

I kept the labels turned down and let folks see if they could guess a few of the species. Most couldn't, although a few picked out oak and maple.
