I know this is an old thread, but I just need to add another use ... hope you don't mind.
I heat my home with wood and like to have a "one-match" fire when I need to rebuild the fire because it has gone out. When I am putting together my kindling for the fire, I include a few small pine cones because they burn for long time and the kindling always takes.
Or if I am bringing a night fire back, I throw a few down on the burning coals before I add my small wood to get my day fire going.
@stone ........
This year I am using the small pine cones in my flower beds under the eves of my house to convince my cat that he does not want to do his business there but needs to search out another spot, of which there are plenty, for that kind of business.
