Definitions for "Leather Hard"
A stage in the drying process of clay when the clay is pliable but strong enough to handle. It is ideal for trimming and the addition of appendages such as handles and spouts. Relatively wet clay can be attached to the pot at this stage and the resulting bond will not form cracks.
