-The gas mixer will mix the input gases based on moles of gas in the ratio provided by the setting, but only if the gases at input 1 and input 2 are at the same temperature.  This means if you're trying to mix [[Volatiles]] and [[Oxygen]] at a 2:1 ratio, make sure both input gases are at the same temperature.

 While the gas mixer ignores input pressures, the mixer will take more moles of the colder gas than you would expect.  For instance, if you set the gas mixer to a 1:1 ratio and both inputs contain just [[Carbon Dioxide]], input 1 at 2000 K and input 2 at 1000K, it will take twice as much of the gas from input 2, so your resultant gas will be Carbon Dioxide at 1333.33 K.

 If you know your two input temperatures and your desired output temperature (which must be between T1 and T2), you can re-arrange this to solve for "S", which will tell you what to set the dial to in order to get the desired temperature:
