I combine sections into manageable sized pieces and put them back down to stiffen more. Finally I layer them and repeat a cycle of cutting across the layers and slamming the mass down onto the table each time. Ten cycles of this produces a thousand layers. After a final wedging the clay is ready-to-use, as good as produced in a vacuum de-airing pugmill!
