Previous "talk" getting misleading.

Untitled[edit]

The article has changed a lot. Previous "talk" references were mostly not correct anymore.

use in salt bridges[edit]

Thermal Decomposition[edit]

Should be added. I found this somewhere on the internet but have no liable source: 4KNO_3(s) → 2K₂O_(s) + 2N_2(g) + 5O_2(g)

Done. Found source, referenced. Riventree (talk) 20:25, 15 September 2012 (UTC)[reply]

More history?[edit]

The history section could really use some expansion into the past. "The earliest known complete purification process for potassium nitrate was outlined in 1270 by the chemist and engineer Hasan al-Rammah of Syria" vs "Saltpeter was known to the Chinese by the mid-1st century AD" in the Gunpowder article. It's as if the first half of its history, before complete purification, was insignificant. 83.14.232.226 (talk) 09:13, 29 May 2015 (UTC)[reply]

"Indian" saltpeter?[edit]

Who ever called saltpeter "Indian" saltpeter? Maybe it is true that they mined it on a reasonably large scale in India, but for a very long time saltpeter was used on a large scale to make gunpowder and England had no commercial relationships with India... I don't know what the Indians did with all the saltpeter they mined, but for sure they did not export it to any English speaking country until modern times.

Wikipedia has very clearly provided the source material—which is particularly rich in its historical discussion for Indian saltpeter—for the reference, q.v. It's simply a question of following the links embedded in the context and looking them up. If you can't find them, I'll give a head-start: "David Cressy.
