I have a bunch of fir/pine bark that is 1-2 inches thick. Like BG, I burn it just to help keep the coal bed going , but only when I burn on weekends.Highbeam said:I just had a bark fire last night, and the night before. The stuff on really old doug fir is inches thick and pops off when dry. It ignites well and smokes only a little. Seems to turn into a huge mass of red hot ash like a cigarrete burning. It puts out quite a bit of heat but I am not holding back with the fuel load either. I think it would burn too fast for the stove and be messy to handle in the house.
