Description of the Object of the Experiment

Potassium process:

The chemical compound potassium nitrate is a course occurring mineral source of normality. It is a nitrate with chemical practice KNO3.

Its common land names include flavourpetre (from Medieval Latin sal petrae: stone salt or possibly Salt of Petra), American English salt peter, Nitrate of potash and nitre. The name salt peter is also applied to sodium nitrate.

Description:

Potassium nitrate is the oxidizing (oxygen-supplying) agent of black powder. Prior to the large-scale industrial fixation of nitrogen through the Haber process, a major source of Potassium nitrate was the deposits crystallising from cave walls or the drainings of decomposing organic material. Dung-heaps were a particularly common source: ammonia from the decomposition of urea and other nitrogenous materials would undergo bacterial oxidation to produce nitrate. It was and is also use as a component in some fertilizers. When utilize by itself as a fertilizer, it has an NPK rating of 13-0-44 (indicating 13%, 0%, and 44% of nitrogen, phosphorus, and potassium, by mass, respectively).

Manufacture:

Historically, nitre-beds were prepared by mixing spread out with either mortar or wood ashes, common footing and organic materials such as straw to give porousness to a compost pile typically 1.5 metres high by 2 metres wide by 5 metres long. The heap was unremarkably under a cover from the rain, kept moist with urine, move often to accelerate the decomposition and leached with water after rough one year. The liquid containing various nitrates was then converted with wood ashes to potassium nitrates, crystallized and refined for use...
