Bruce-

Couldn't you use the formula which determines the change in the molar values 
of the ingredients in water to determine the freezing point? In other words, 
if you've got X moles of solute in Y moles of solution, the important temps 
(freezing point, boiling point, vaporization point) change at a fixed rate.

Of course, me being me, I'd just get some superquench and a thermometer, 
throw it in the freezer, and check on it every so often, see if my freezer 
went down low enough to freeze it.
