This appears to be a drying crack, but it is not

Tuesday 12th July 2016

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.
