Smelting one Lead Ore produces the following gases:
|0.4 mol||Carbon Dioxide|
|0.4 mol||Nitrous Oxide|
Putting lead ore in a Furnace or in a Advanced Furnace already working will increase the pressure and lower the temperature, this can be useful to reach some furnace state like the needed to smelt Waspaloy.
