As stated above. Some metals and stuff are fine if you were to throw them into say, a camp fire, so to smelt them you need… hotter fire? How does one achieve that hotter fire and how/ why does it work?
In: Chemistry
Fire is a chemical reaction that generates energy – the temperature reached depends on how much mass there is, how much is reacting (I.e. burning), and how much is accumulating vs being lost (such as to the wind in a camp fire) – so to get higher temperatures, insulation (like brick ovens) can get higher temperatures, more reaction (I.e. higher surface area of wood, using pure oxygen vs warming up non reacting chemicals like nitrogen or water trapped inside the wood, maybe even bellows if the air is the limiting factor)
