Sorry. I wouldn't use these any more than I would yellow snow in my whiskey. On the rocks was meant to be rhetorical not literal.

Soapstone has a heat capacity of 0.94 J/g-K or 3 J/cc-K if you take the density into account.
So, let's say you cool these to -4 degC and put 1 cubic centimeter's worth into 10 cc of water at 20 degC (roughly room temp).
For every 3 J of heat absorbed from the water, the cubes will increase in temperature by 1 degC.
Water has a heat capacity of 4.184 J/cc-K, so for every 3 J lost to the stones, the liquid temperature will fall by 0.072 degC. The equilibrium point in this case will be at 18.4 degC when the 10 cc of liquid have transferred 67.2 J to the stones, raising their temperature by 22.4 degC. Not much cooling when the stone:liquid ratio is 1:10.
Now do the same thing with 1 cc of -4 degC ice instead of stones. Ice has a heat capacity of 1.932 J/cc-K. It also has an enthalpy of fusion (or melting) of 334 J/g. So, the ice would absorb 7.73 J getting to 0 degC, then absorb another 334 J melting completely. This would bring the liquid temp down to 8.2 degC. The newly formed water is still at 0 degC, so it would bring the net temperature of drink down to 7.5 degC. In conclusion, the ice cools way better that the stones, largely because of the phase change. Of course is also dilutes your liquid by a little - about 10% or so.
Whiskey has a large ethanol component, with a heat capacity of 1.77 J/cc-K. This would mean slightly better cooling with the stones than in the example above, but way better cooling with the ice.
If you want cold with out dilution either chill the glass in the freezer or mix -4 degC spirits with room temp spirits in the ratio that gives you the target temperature you want.
The rocks don't do much thermodynamically.

I was watching METEORITE MEN last night during clue, I wonder if anything tonight on TV will match up with the woot item.
Where did I put my my quill and inkpot?
