Leather Hard - Clay which has dried sufficiently to be stiff, but is still damp enough to be joined to other pieces.
Bone Dry - Clay that is completely dried but not yet fired. Clay forms are most fragile at this stage.
Projects from this semester:
When connecting slabs, it is important to have the clay leather hard so that the clay will keeps its shape, but still have enough moister to connect with other slabs. Having the clay to wet will cause the structure to be misformed or collapse. Have the clay too dry with cause the slabs to come apart.
