Ironman verdict
Saltpetre is a members item. Other players trade it, but an Ironman cannot use the Grand Exchange or trade, so you get your own. We list 4 other sources for it.
It does not drop from monsters and no shop stocks it. It comes from 4 other sources, including Extra supply crate, Ancient chest and Saltpetre (deposit).
It is a material in 2 recipes: Dynamite pot and Sulphurous fertiliser (36 Farming). High Alchemy (55 Magic) turns one into 3 coins. Each cast uses a nature rune, 180 coins from a rune shop, and five fire runes that a fire staff replaces, so an alch loses about 177 coins; only alch it to clear space.
