"Whiskey Stones" - ice, stone, steel: which is best?? The conundrum: I'd like to purchase the most effective cooling item for my evening dram of scotch, or Manhattan bourbon, or Black Label, or... Where was I? Seriously, I am intrigued by the growing popularity of "whiskey rocks" - an item to replace ice - and am curious about both the science and marketability behind them. The basic idea is that a cube of glass, soapstone, or steel keeps the drink cold like ice cubes but does not melt and spoil the whiskey taste. My main question: Which material will keep my drink at the lowest temperature for the longest - glass, soapstone, or steel? And, more importantly, will this material cool my drink to a temperature that is close enough to the temperature of an ice-cooled drink. Assume that the material can sit in the freezer for days (i.e. the time required in cooling is irrelevant). Assume for simplicity that cubes of each material have the same mass and surface area (though, that's a fiction). Thoughts: I'm working it out now, but haven't used these equations in almost 10 years. I mainly figured that it would also be an enjoyable headscratcher for PFers to discuss! My initial hunch is that nothing gets my drink nearly as cool as water (4.186 J/gK Degree heat capacity) because only soapstone gets the closest (0.98 J/gK). But, if that turns out to be true, I just have to figure out if soapstone cools it enough to drink with pleasure, or if it's just a matter of accepting some ice-melt... Cheers!
