I bought a few packs of these due to a shortage of seasoned wood later in the heating season....I figured about mid Febuary. I threw one in earlier today to see what it does. Stove was at 400.....nice bed of hot coals....throw in one brick....flames develop around bottom....then up sides and ends....they roll around the top and flame about 5 inces high.....one hour into the burn....stove temps at 301....and the brick is a smoldering block.....what gives ????....the air was full bore......thru in a piece of Hickory to finish the smoldering block.
