Final answer:
Clay can be recycled by dehydrating it on a plaster surface and then using a 'pug mill' to achieve a homogenous consistency.
Step-by-step explanation:
Clay can be recycled by dehydrating it on a plaster surface when it is too wet and then mixing it in a 'pug mill' to achieve a homogenous consistency. The process of dehydration involves removing the excess water from the clay, making it easier to handle and shape. The 'pug mill' is a machine used in pottery production to mix and blend the clay, ensuring it is uniform and ready for use.
