I have Sub-Bituminous "C" coal, caricterized by lots of volitals, initial smoke.
Sounds like you have Sub-Bituminous "A" coal, caricterized by low quantitiy of volitals.http://www.miningbasics.com/sub-bituminous-coal
I wish I had a better link,
Any chance you can find out more information on your coal?
It sounds great, and there is no chance I will make the trip to get some, just courious about the official type.
