That's not rust, it's Canadian patina...
Mace, with all due respect... you can't change the melting/freezing point by changing the temperature..
Hmm, maybe we should look at using some of this... (if'n youre really bored...)
"
Supercooling occurs when a liquid is cooled below its equilibrium freezing temperature. For example, water can sometimes be cooled as much as a few tens of degrees below 0°C without freezing. This phenomenon is important in cryobiology. See also What is 'unfreezable water'?"

Water freezes and melts at 32* f (0*c)
That melting point/freezing point can be altered by changes in Pressure and temp.
