Talk with your clay supplier and tell him what you want in the claybody (ie:
throwable if you throw, and weather resistant.) You want a body that is
vitrified at whatever temperature you're firing, because if it's not
vitrified, water will get into the claybody and break it when it freezes.
Highwater's Riverside Grit is good for outdoor use at cone 6. I made a
headstone with that for the first hen we lost in 2001, and it's been out
there ever since.
