FAQ
Frequently Asked Questions
No. Table salt is sodium chloride (NaCl). Saltpeter is potassium nitrate (KNO₃), a different chemical compound with different properties and uses.
It follows the common British-American spelling pattern where words of Greek/Latin origin often end in '-re' in British English and '-er' in American English (like centre/center).
In tiny, regulated amounts, potassium nitrate is approved as a food preservative (E252), primarily for curing meats like salami and ham. Consuming it in its raw, concentrated form is dangerous.
That is a different compound: sodium nitrate (NaNO₃), which was mined extensively in Chile and also used as a fertilizer and in explosives. It is not potassium nitrate.
