Nitrary

A typical nitrary (Germany, circa 1580) with leaching deposits (C) filled with decaying vegetal material mixed with manure. A worker collects efloresced saltpetre from deposits, transporting it then to be concentrated in the factory (A) boilers..

A nitrary is a place of production of potassium nitrate or saltpetre used primarily for the manufacture of gunpowder. The saltpetre occurs naturally in certain places like the "Caves of Salnitre" (Collbató) known since the Neolithic –Cova del rat penat– the guano (bat excrements) deposited over thousands of years became saltpetre after being leached by the action of meteoric water.
