A saltpetre works or nitrary [1] is a place of production of potassium nitrate or saltpetre used primarily for the manufacture of gunpowder. The saltpeter occurs naturally in certain places like the "Caves of Salnitre" ( Collbató ) known since the Neolithic.
Potassium nitrate can be made by combining ammonium nitrate and potassium hydroxide. NH 4 NO 3 + KOH → NH 3 + KNO 3 + H 2 O. An alternative way of producing potassium nitrate without a by-product of ammonia is to combine ammonium nitrate, found in instant ice packs, [30] and potassium chloride, easily obtained as a sodium-free salt substitute.
After the water evaporated, the potassium salts crystallized into beds of potash ore. These are the locations where potash is being mined today. The deposits are a naturally occurring mixture of potassium chloride (KCl) and sodium chloride (NaCl), more commonly known as table salt. Over time, as the surface of the earth changed, these deposits ...
