IL THERE HAS NEVER BEEN Crimolois iron mines, the soil is not
FERRUGINOUS
What the ancients called the mine was actually a place where you made the ore with charcoal
holes in the ground were the crucibles, about the Smaller holes are still visible legacies of the bombing of the Italian 1940, when Dijon was declared an open city ... (in war anything goes).
HISTORY CHARCOAL
Catalan In the method, the ore is heated with charcoal in a crucible square masonry. We begin by garnishing the crucible of charcoal ignition, which is loaded side-by-side ore and coal, the latter in double quantity and is disposed in the vicinity of the nozzle inlet; under the action of the strong current of air from the wind, coal burning;
carbon dioxide, formed by the combination of oxygen and carbon, is transformed into carbon monoxide on excess layers of coal brought to the nearby red carbon monoxide is then passed through the mass of ore, partially reduced state of iron metal, while it turns itself back into carbon dioxide ... Expeditious method,
low yield, requires a rich ore, and timber in abundance .... who had nevertheless the merit of allowing the birth of iron metallurgy.
From an economic perspective, charcoal and coal have long been an important resource for the neighboring populations of forest and metallurgical facilities. Similarly for the carriers responsible for transport of ore and charcoal, as the boatmen of the Isere were put to use to transport the ore
without charcoal metal would not exist
