High-fired clay is way too hard to practically crush for
use as grog.
Maybe some kind of heavy duty commercial roller or crusher
could do the job, but this is way beyond anything a potter
would have. Even a hammer mill is not up to this task; it
would wear down the hammers in no time.
You cannot ballmill because it would give you smooth, rounded
particles, and for grog you want angular pieces.
I grind up broken bisque ware for use as grog in my hammer
mill. Some of these pieces are broken after glazing, and the
glaze is not a problem in the claybody.
