Jewel, The few things I have read that talked about ice before the days of refrigeration mentioned that large blocks of ice were stored in caves or in ice houses underground where the ambient temperature was in the mid 50 degrees F, about 12 degrees C. Thick layers of saw dust were placed between the layers of ice. apparently this was enough to keep ice through the summer. They actually used to ship ice from North America to England long before steam ships or refrigeration.
About the salt though. The salt actually promotes the melting of ice, that is why we throw salt down on our driveways and roads during the winter time. the key is that it takes a lot of energy for ice to turn to water. For example it takes a lot more energy for a piece of ice at 0 C to turn to water at 0 C than it does for the same mass of water to go from 0 C to 1C. -- Blue skies.
