Well, last September I cut and split some sweet gum. Had no idea what I was getting into. Anyway, it has been c/s/s since last September, so seasoned a little over a year. I wrote here about it to see what kind of wood was that hard to split. I remember somebody saying that it burns like crap and does not have much in the btu department. Now, my question. What does it burn like? I am burning it right now, and whenever I toss a log in the furnace, I get a lot of smoke from it as it ignites. Is this how seasoned sweet gum burns, or is the log just not seasoned and that is steam coming from it. I just find it really hard to believe that the logs are not seasoned after a year where I had them, but I have ZERO experience with sweet gum. For all I know, it has to be seasoned like oak. Oh yeah, it also produces a ton of ash. Edit to add: Just threw two more pieces in the furnace. One smoked like crazy for about 30 seconds and the other hardly at all.
