Slab pottery is exactly what it sounds like – pottery made from a flat sheet of clay. Unlike the other hand-building methods (coil pottery and pinch pottery), you make your constructions using flat slabs of clay cut to specific shapes and sizes, which are then joined together with scoring and slip.
Take clay and place it on the slab roller table. (Use 2 slab matts: one under the clay and one on top of the clay)
Roll the slab roller's canvas over the top slab matt.
Turn the wheel to run over your clay.
Turn the wheel back to release the clay.
Take your clay and slab matts.
