Why Does clay have a memory?
Memory is caused by the loss of water content. As moisture is lost, the yield point increases until the maximum green strength is achieved. As drying occurs, the uniform negative charge reverts back to neutral, which in turn causes disorientation of the particles. Once the water leaves the clay, so does memory.
What is the slab technique in pottery?
The slab technique starts with smooth slabs of clay that are then formed around molds or shaped by hand.
