Amazon has 5 pounds for USD 27.98, free delivery. Speaking from experience
it sucks as a stump remover. You're supposed to drill holes, pour the
solution in, wait a few weeks, and set fire to the stump. Good luck with
that.

I wonder if anyone ever uses it as stump removed or if everyone who buys just uses it for pyrotechnics? ;)
Sulfur is a bit more difficult to get though. I think it is on some kind of "watch list" where you need a license or a specific reason to buy it. =(
This I can buy without problems though:

And contains 80% sulphur. So I had to mix it with water, and then wait for the sulphur to sink to the bottom, pour off the other stuff that formed on top, and then it could be used. I do have my doubts about the quality, but it did work in the classic gun powder mix, although it was very slow burning but I suspect that
1. Adding high quality coal and
2. Purifying it with alcohol
would increase the speed at which it burns. Maybe I'll try it again this summer! =) It is a fun hobby!
