AKA Saltpeter. I've heard that you can just dig the stump out after a few months, in addition to using fire. I bought some to remove a stump a few years ago, but when I went to drill the stump I found it had already rotted enough that I didn't need it. This was a small, maybe 10" diameter, stump that had sat for a couple years. Going to see how well it works soon though; a few weeks ago had a ~2ft diameter stump left when my 65ft spruce snapped in a wind storm. Turns out about halfway up it had branched off into two trunks, and that junction was rotting, the wind storm caused that junction to snap half way up. In looking, my neighbor has a tree with the same dual-trunk situation, though hers is more likely to land on her house.
