The Basics of Wheel Throwing

1. Wedging the clay

The purpose of wedging the clay is to work all the air bubbles out and evenly distribute the moisture throughout the piece of clay. It’s done by pushing the clay over and over again on a wedging table, similar to kneading dough.

2. Centering the clay on the wheel

The first step to making a pot is centering the clay. Place the clay as close to the center of the wheel head as you can. Apply enough pressure with both hands working opposite of each other so that the clay begins to move. As you apply pressure the clay moves upward. Then by placing your right hand on top of the clay you press it downward. These steps may need to be repeated several times to bring it into center.

3. Flatten and check for thickness

Once the clay is centered, flatten it some, then press thumbs down in center of the clay to open it up, being careful to leave a thick bottom.

You can check the thickness of the bottom with a needle tool. For most pots, 1/4” is perfect.

4. Opening & compressing the pot

To open it up further, place fingers of both hands to the inside, pulling carefully towards you.

Next, compress the bottom with a wooden rib to strengthen the bottom. Without this step, the bottom could crack during the drying or firing process.

Apply pressure from both the inside and the outside as shown. This will prepare the walls for the pulling.

5. Pulling up the walls

Apply equal pressure by both middle fingers on the inside and the outside of the pot simultaneously, working opposite each other. Then hold the pressure and pull slowly upward. The wall will grow taller and thinner.

6. Smoothing

Continue to pull the walls until the thickness on the side is about 1/4”. Then place the rib against the outside of the clay wall . With your hand, gently press the clay into the rib. This will smooth and straighten the walls.

7. Trimming

With a wooden knife, cut into the foot of the pot at an angle, trimming only 1/4” inward. With the needle tool, trim the top of the pot if necessary (if it is uneven). Then use a sponge to smooth the lip. Now you are ready to shape the vessel.
