This clay normally dries well, but not this time. Strangely, this crack is not at the handle join, it is penetrating into the mug wall. Actually, this is not a crack, it is a split. Excessive slip around the join was not removed, that is bad when a body has larger particles, they permit water left on the surface to penetrate inward and begin a split. An aggravating factor was that the handle was allowed to dry faster than the mug itself, pulling at this join and opening the split even more.
