In which case the ice cools about 100 times more (& faster, as that energy is absorbed per unit surface area) than the soapstone.

So not only does the soapstone cool the drink faster, but it also cools it more. only catch is, its about 3 times as heavy. but i'm sure we can all live with that. you’ve still got your physics wrong. specific heat capacity is how much energy is absorbed/emitted to heat/cool 1 gram by 1 degree. if you want speed of transfer of energy, that’s the second law of thermodynamics (not the first), which i suppose would be surface area times temperature difference. since the stones are porous i suppose they’d have a much larger surface area.

I reckon in most cases though, the drink will have been drunk before it warms up that much. If the stones warm up faster, then the drink cools faster too, right? So maybe stones are also a good way of cooling drinks quickly. True, and like you said I guess it’s a trade off.

Surely, the lower SHC means that the stones will 'melt' (ok, warm up) 17.88x faster than your standard ice cubes? So it's presumably a trade-off between having a cold drink for longer, or having it becoming more diluted. I thought I’d got over my chemistry thing, but clearly not…
