Yes, the importance of insulation was already documented in-depth. However, this is a relatively common question amongst buyers and it deserves to be addressed individually. As was talked about before, the actual design of an ice bucket will pay important dividends to how long the ice will actually stay chilled and frozen. With that said, there are also a number of key variables that will accelerate the melting process. For example, if you leave the bucket out in the middle of the sun in scorching heat, the ice will melt faster than it would if left in your refrigerator. Also, you may want to place larger cubes inside to ensure they last a bit longer.
