Back to mild weather here again, darnit. I put in half a load of 100% pine cause everybody says the house is too warm. Burnt fast as planned, just right for the day. Started with no ashes after morning cleaning and now still have nearly no ashes when done. Guess I don't remember that stuff leaving nothing but you start out with half the fiber weight by volume. BTW, nothing wrong with pine, my opinion. Just relit with BL for overnight burn.
