Kosher salt melts ice faster!

Hi,

I run an experiment twice and had same result and don't know why. 5 containers with the following: 15g ice cube and one of the following: 5g of kitchen salt, 5g of kosher salt, 5g of rock salt, 5 grams of Epson salt (magnesium sulfate), 5g of sugar. The control was a container with a plain ice cube. Both kosher salt and kitchen salt had the same caking agent. Kosher salt had slightly large particles than kitchen salt. Results: Kosher salt mel ice first, followed by kitchen salt, rock salt, Epson salt and finally sugar. Plain ice cube melted last. Why is that?

Please help.

I didn't find the right solution from the Internet.
