I went to visit the coal yesterday and the lady was nice enough for me to inspect and get a feel on what I will be hauling out of her basement. I'm not sure of the exact differences between Bit and Cannel coal, but one thing for sure is that it did not light the easiest. I picked a sharp corner, relatively thin and lit it with a lighter. Had to hold the lighter there for 30 seconds or so before the corner of the coal ignited on its on. Extinguished itself after a few seconds and it smelled like bit coal (I have other bit coal from a steam locomotive to compare it to and the smell was identical), def that sulfur bit coal smell. Not bad but definitely there. (Does cannel coal have a bit like smell?)
It was hard to break, I could even not break it by slamming it on the ground. It did not feel dense like gravel, I would say, one thing for sure that this is NOT anthracite. Not glassy, just a dull grayish black with some shiny waxy deposits on it. I was able to use it as chalk and mark up a concrete floor when I drew with it. I figure I can take it off of her hands anyway...it is difficult to get bit coal up here in New England and I can always use it in conjunction with an outdoor wood fire or for camping purposes. A few pounds of coal thrown in an open wood fire could go a long way in extending the fire a bit and is cheaper and cleaner than hauling firewood in the car. Even if not cannel coal, I could find some use for it in those ways.
