 | | Potassium nitrate, also known as saltpetre, is a commonly used chemical (used, for example, for pickling meats, and in toothpaste for "sensitive teeth") and as such is quite readily available. |
 | | Potassium nitrate is also sold as 14-0-45 fertilizer at farm supply stores, typically 98-99% pure.This is by far the most economical form, and the performance is no different that purer grade. |
