So I burned for two days and this is the resultant ash of that burn. I didn't have the stove turned up over 1 on the bi-metal thermostat at any time during the burn and had it lower during the days. As you can see there is not much ash for those two days so I assume that is good, no? What does concern me is the reddish color of the ash, as you stated above this could indicate the possibility of a lot of clinkers. The heat output seemed to be very good and It was easy to maintain over those two days but not a large sample to form much of an opinion on that.
I would just like your opinion on weather it is a major concern of the red color of the ash, BTW this coal is from the Gail mines.
I appreciate any and all insight.
