(With the proper high temperature of 450°C)
|Mist and fog are a mixture of steam-gas and water droplets.||
Proper high temperature steam gas has no water droplets.
The pictures above are for the illustration of the color difference between mist and good steam.
The nozzle-exit is at a high temperature in both pictures, however,
when the temperature is not high-enough (left), mist can be seen down-stream (translucent).
When at a proper high temperature, only steam-gas (colorless) is experienced.
Mist does not posses antibacterial properties like high temperature steam can provide.
