After scoring, you will brush slip on each side as if you are gluing the sides together.
First, place your clay on the cloth of your slab roller and spin the wheel to move your clay through. Then, use a pointed tool to trim the slab to your desired size. You may make paper templates to follow to map out your project and cut the slab accordingly. You can also use a slump mold to create uniform shapes for things like plates and bowls. In this case, you would roll out your slab and drape it over or inside your form. Finally, you will join the two slabs together using a process called “score and slip.” Scoring your clay is essentially scratching marks on the two sides that will be joined together. After scoring, you will brush slip on each side as if you are gluing the sides together.
