Bone-Dry Clay Vessels: Formed, Dried Slowly, Ready to Fire
A pot must be bone dry before it is fired: dried until it is porous, no longer plastic and very fragile. On the way it passes leather-hard, when shrinking stops. Dry it slowly and evenly so it does not crack, and finish the last water off gently in the kiln.
The picture: a large unfired pot, bound round with fibre while it dries, at Nwenyein, Myanmar.

Dry slowly under cover
Stand the pots on a cloth-covered board out of sun and draught, loosely covered, so rims and bases dry at the same pace.

Leather-hard
Leather-hard
When the clay is firm enough to handle and has stopped shrinking, it is leather-hard: trim and burnish now, and join handles with slip.

Uncover and dry to bone-dry
Uncover and dry to bone-dry
Uncover the pots and let them dry in a warm room until they turn pale and light. A pot that still feels cool against the cheek is still damp (our test). Handle bone-dry pots gently: they break easily.

Leather-hard and bone-dry are as the Wikipedia ceramics glossary defines them; the cover, the cheek test and the weighing are ours. Kilns finish the last water with a slow, low first stage (candling).
