My main concern would be to make sure the rocks have time to acclimate to room temperature before cutting or grinding them.  In the winter here, it can be -20 outside and we keep it in the 60s inside.  I find that my preforms from upstairs chip and crack less when i use luke warm water rather than cold water from the faucet.  Cutting and grinding heat up the stone and if the water is cold, there can be quite a temp difference between them.  Maybe this isn't that big a deal in some warmer climates, but I have a lot less problems with cracking and chipping now.
