Hollow Clay Sphere

Knowing how to make a hollow clay sphere is really useful for making fun sculptures. (For those of you who are new to working with clay, your clay can't be too thick without running the risk of it cracking or exploding when fired.)

I learned the following technique at a fabulous pottery class taught by MaryAnn Guerry through the Lake Stevens Community Education Program.

Making a hollow clay sphere:
1. Roll two equal balls of clay.

2. Plunge your thumb into the center.

3. Start pinching the sides out to form a "pinch pot."

4. Continue to work your ball into a bowl by pinching out the edges, with special care to keep all sides and base an even thickness.

Here are my two finished pinch pots:

5. Turn the edges of one pot in, and the edges of the other out...then score rim with fork, toothpick or other such utensil.

6. Dampen the edges by dipping your finger in water and running it along the scored surfaces.

7. Align the scored edges...

8. ...then blend the rough edges away by smoothing the clay together with your fingers. After all the seams are sealed you can even roll it on the table to work it into the shape you want.


I threw a silly little face on this one just for fun...although I squished him just after taking this photo. This block of clay is goofy so I want to try and exchange it...notice how the clay is cracking...this shouldn't happen. Poor wrinkled old man.

(I used this hollow sphere technique to make the dragon piggy bank in one of my previous posts...check it out here: Piggybank Dragon.)
