Any pharmacist should be able to get you some saltpeter (or saltpetre),
but at least here in Minnesota they won't; I guess they are afraid we're
gonna make gunpowder or something. You can try your luck in Boston.
"Gordons Stump Remover", available at gardening centers is potasium
nitrate. I called the company to make sure it was KNO3 and not NaNO3.
It seems to have a waxy coating that doesn't disolve, so crunch up the
little white KNO3 balls (called "prills") and then filter the solution
with a fine mesh tea strainer after you disolve them.
