So, last night I had too many ashes and coals in the firebox of my insert, could hardly fit a full load of wood in there. At 11:00 pm I shoveled a bunch out into a metal bowl I borrowed out of my charcoal smoker. Yea, I need to get a metal bucket I know. Anyhow, I set it out on the concrete patio. It was snowing last night, we got around 8 inches here. I woke up this morning, went to work, came home, and after dinner decided to put the ashes, which had sat out in the snow all night, into a bag and put it in the garbage. That's when I noticed it burned right through the bag! I can't believe I had red hot coals in the ashes almost 24 hours after putting them outside, in the snow no less. The temps were in the mid teens last night, and never got over 26 degrees today. Lesson learned...
