Don't try this at home, or at least indoors:
Once consolidated from all sources by dissolving in nitric acid, the solution was boiled and evaporated into a crude nitrate slug. The slug was fired in an air-blown wood oven in a loosely closed ceramic vessel. The nitrate decomposed by evolution of toxic, corrosive nitric oxide gases (NO2 + N2O5) with a characteristic red-brown color. Gases escaped a safe distance away from human activity. Black metallic powdered silver remains in the ceramicvessel. If melted with a welding torch, it is bright, pure silver! It took a couple of days.

Certainly some science involved there. Very interesting
