Just thinking of how you might speed things up, esp. if you're cutting several bottles: Once you get a bit of crack going in the bottle, stop and dip it in water. Then put it in the freezer while you go to the next bottle. Only a little water will get into that crack, but when water freezes, it expands! That may convince your bottles to crack faster in the long run.

I remember that from my tour to the Colosseum in Rome: Only male urine because there were no restrooms for women there(!), and only from the upper class patrons, who had separate public toilets with troughs where the urine was collected.
