Definition:
Leather-hard (adjective) refers to a specific stage during the drying of a pot or other clay object. At this stage, the clay is still visibly damp (usually a darkish gray) but has dried enough to be able to be handled without deformation. The clay is able to be gouged or incised without breaking, but will not receive impressions.
The leather-hard stage can be further refined as soft leather-hard, leather-hard, and stiff leather-hard stages.
Examples:
Leather-hard greenware is cool to the touch.
