Saltpeter is a non-economic and low-value yellow stone found within sedimentary layers. With a melting point of 10601 °U and a boiling point of only 10720 °U , it is one of the few stones which will boil in magma.

In real life, it is used in conjunction with charcoal and sulfur in order to make gunpowder. This process does not exist (yet; it seems Toady has plans to include gunpowder later, but only for simple uses) in Dwarf Fortress, and therefore gunpowder is also non-existent.

This article or section has been rated D for Dwarf. It may include witty humour, not-so-witty humour, bad humour, in-jokes, pop culture references, and references to the Bay12 forums. Don't believe everything you read, and if you miss some of the references, don't worry. It was inevitable.

It is rumored that if a dwarf ever discovers saltpeter's capabilities, dwarven "civilization" would come to an explosive, but Fun end.
