Melting Ability vs. Temperature




1 LB.
of Salt Melts


46 lbs. of ice


14 1/2 lbs. of ice


8 1/2 lbs. of ice


6.1/2 lbs. of ice


5 lbs. of ice


4. lbs. of ice


3 1/2 lbs. of ice


3 lbs. of ice

You can see how quickly salt's effectiveness drops as the temperature does. This is why Calcium and Magnesium are being used in many blended de icers.
There is a MAJOR drop in effectiveness from 30 to 25 degrees. The largest drop on this chart, about 32 pounds less ice!!!
Now do you see just how much temperature affects melting properties of salt?
