In his De re metallica Agricola gave several methods of obtaining the metal by simple liquation of the native bismuth or by reduction with charcoal. Pulverized charcoal was placed in a small, dry pit, and a fire of beech wood was kindled over it. When the ore was thrown into the fire, the molten bismuth dripped out of it into tire pit. The solidified cakes were later purified in a crucible (24).

The Probierbuchlein contains elaborate directions for making sets of standard touch needles for comparison with alloys to be tested by their streak on the touchstone. These sets are composed of alloys of silver and gold, silver and copper, gold and copper, and gold, silver and copper. Each set numbers, usually, from twenty to thirty needles. Agricola s De Re Metallica incorporates these in his more systematic account. 

The description of sources and methods of obtaining and purifying saltpeter is the earliest complete account of the preparation of that salt. It is apparently the basis of the somewhat condensed description in Agricola s De Be Metallica. Biringuccio says that saltpeter (sal nitro) is a compound of several substances, extracted by fire and water from dry earth containing manure, or from the efflorescence produced on new walls in damp places, or from the mouldy earth which is found in tombs or in unoccupied caves where rains cannot enter. After describing its physical properties and its explosive character, as in gunpowder, he continues ...
