Stone Cold

The stone was covered with tarps which helped keep the snow off, but not the cold.

Eric and Jordan and I worked in the cold on Tuesday but discussed warm memories and retold funny stories.

It seems to me that stone ( limestone at least ) cuts differently when it's frozen. It's more unpredictable, and tends to scallop more, and break in curves, rather than straight planes. Has anyone any thoughts on why this might be? I would have thought stone would split better ( like fire wood does when it is frozen).

Another challenge working with cold frozen stone is making sure all the ice and frozen mud is chiseled off the surfaces of the stones before they are laid in the wall. This can be almost more difficult than shaping the stone itself.

  1. Could it be because limestone is a fairly porous stone and when
    the moisture content inside the stone freezes it would cause different
    pressure points that may not be there in warmer days and cause it to
    crack unpredictably ?
