Ce n'est pas clair, mais c'est fort probable que le plupart des decouverts etait fait par hasard en faisant la cuisine. Si le feu de camp etait etabli sur un minerai metallique, c'est arrive parfois une chose inattendue, mais heureuse.
Un tel accident ou deux pouvait provoquer des experiences systematiques par suite.

Les peuples de l'Antiquité extrayaient les métaux des minerais en utilisant des techniques telles que la fusion, la fonte et la séparation chimique. Ils chauffaient les minerais dans des fours pour en extraire les métaux tels que le fer, le cuivre et l'argent. Les Premières Nations utilisaient des techniques similaires, comme la torréfaction et la séparation manuelle, pour extraire les métaux des minerais qu'ils trouvaient dans la nature.
