    • When Xena is trying to figure out the components of the black powder, she says it has sulfur, charcoal, and something else she can't identify, which Joxer later identifies as a meat curative. This third ingredient is potassium nitrate (a.k.a. saltpetre), which can be found as a crystal on cavern walls, or made by the refinement of urine or a combination of manure and wood ash. Potassium nitrate was, in fact, used in salted meat as a preservative, but has mostly been replaced by more modern nitrate and nitrite compounds. It is still sometimes used in making corned beef and salami.
