Information On Potassium Nitrate From Wikipedia

Potassium nitrate is a chemical compound with the chemical formula KNO3. It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate.
It occurs in nature as a mineral, niter. It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter or saltpetre. Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and generates a pink color.

Good Stuff

This is good quality Potassium Nitrate, lab quality, and all it is advertised as being. For some applications, it may be best to reduce it in size via a blender or a pestle. Wish it was a bit finer, to eliminate the extra step, but overall....I will take the good quality and not complain too loudly.
