4. Tools Anything will work!

5. Methods of sculpting with Clay • Pinch Pots or Modeling with clay • Coil Building • Slab and Slip Methods

6. Modeling clay into a pinch pot. Start with a ball. Push thumb into center. Pinch from bottom upward. Shape and smooth for finished pot. ReviewMethods

7. Modeling clay using coil method Roll clay into coils or “snakes” Attach using the slip and score method Rolling spirals Spheres or Disc shapes ReviewMethods

8. Sculpting with the Slab Method Flatten clay Roll and cut to size Score and Slip Join and reinforce Smooth with tools Finish and repeat ReviewMethods
