The two scientists discovered that saltpeter formed inside the walls of the caves of the doline, under certain conditions of humidity and temperature. [9] Prior to the discovery, nitraries were widespread all over the Kingdom of Naples. Manure was collected by the government and used to make saltpeter, which was a key ingredient for gunpowder ...
Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3.It is a potassium salt of nitric acid.This salt consists of potassium cations K + and nitrate anions NO − 3, and is therefore an alkali metal nitrate.

This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter. Sodium nitrate is a white deliquescent solid very soluble in water.
Humberstone and Santa Laura Saltpeter Works are two former saltpeter refineries located in northern Chile.They were declared a UNESCO World Heritage Site in 2005, as a testament to the historical importance of saltpeter mining in Chile and the culture and social agenda that developed around it in the late 19th century.
Niter or nitre [5] is the mineral form of potassium nitrate, KNO 3.It is a soft, white, highly soluble mineral found primarily in arid climates or cave deposits. Historically, the term niter was not well differentiated from natron, both of which have been very vaguely defined but generally refer to compounds of sodium or potassium joined with carbonate or nitrate ions.
In India, guns made of bronze were recovered from Calicut (1504) and Diu (1533). [263] By the 17th century, Indians were manufacturing a diverse variety of firearms; large guns in particular, became visible in Tanjore, Dacca, Bijapur and Murshidabad. [264] GujarÄt supplied Europe saltpeter for use in gunpowder warfare during the 17th century ...
The location, named Eleutherian Mills, provided all the necessities to operate the mill: a water flow sufficient to power it, available timber (mainly willow trees) that could be turned into charcoal fine enough to use for gunpowder, and close proximity to the Delaware River to allow for shipments of sulfur and saltpeter, the other ingredients ...
