Wheel Throwing

I wrote this for Not Made in China Pottery Studio

If you’ve seen the movie Ghost, you know what wheel throwing is. “Throwing” is the term potters use for building clay vessels on the wheel. There are several steps to throwing. The first step is called centering. In centering, you slam a ball of clay onto the wheel with enough force to make it stick. Using a sponge, add just enough water to make it slippery. Use your left leg as force behind your arm and wrap your hand around the clay to push it up. Your other hand should be behind but not pressing hard. To push the clay back down, have your arm against your stomach and push away from your body. Do this several times until the clay doesn’t move when you place your hands on it.

After the clay has been centered, you’re ready to open up your piece. Place your hands on either side and dip your thumbs in to create a well. Press down close to the bottom of the piece. Using a needle tool, measure to make sure the bottom is about three-quarters of an inch thick. Use a tool to flatten out the bottom. Now you are ready to begin building the walls.

To build the walls, hold one finger on the inside of the vessel and the other on the outside. Use your thumb on the outside wall to make a groove. Bring your fingers up to the top of the vessel and let go gently. After your walls are at the desired thickness and height, you’re ready to shape the vessel.

To shape the vessel walls, hold the tool at up to a 45-degree angle. Turn it until the walls are at a desired shape. Now you are ready to remove the vessel.
To remove a finished piece, use a wire tool to slide beneath it. Wet the wheel with water to create a slippery surface. Reach your hands behind the piece and gently push it off the wheel onto a bat or other flat surface.
