The workshop guide to ceramics

There are two main methods of slab building, which are dependent on the condition of the clay before forming. The sheets of clay may be either fresh and soft (soft slabs) or partially dry (leather-hard slabs). Soft slabs will allow you to manipulate and alter them by bending, folding, pressing and stretching as you build. Hard slabs allow you to construct complex, angular, sharp-edged forms as though using sheets of wood.
