Freezing Point Elevation

Question: Is there any way to raise the freezing point of water? I
understand that adding salt or antifreeze will lower the freezing
point. I would like to create ice at a temperature above 32 degrees
F. Is that possible?

John,
 
I can not think of a way to raise the freezing point of water 
significantly. Dissolving anything in water will always lower 
the freezing point of the resulting solution. I thought that 
one could increase the freezing point of water by reducing the 
pressure. However, the highest freezing temperature is a change 
of +0.0098 degrees centigrade, so there is not much gain there. 
Maybe some other members will have better ideas.
