What Is Wedging Clay?

Wedging is a process used to transform clay that is not ideal for working (either because it’s either too dry, too wet, or is inconsistent and lumpy) into a homogeneous ready-to-use consistency once again. Wedging is an essential technique for a potter to master, and will help ensure smooth and successful form building (whether in slab work or wheel throwing).

What Is The Purpose Of Wedging Clay?

Wedging may seem like a simple enough task in the pottery studio. But any potter who has used recycled clay will know that it’s important not to overlook proper wedging technique to avoid air bubbles and other potential problems.

The wedging process, when doe correctly will accomplish a number of things:

  • It makes use of recycled clay, restoring it to usable condition
  • Mixes the clay and removes excess moisture (particularly when using an ideal clay wedging board / surface)
  • Removes air pockets from the clay + aligns the clay molecules

How To Properly Wedge Clay

Technique can vary, but this video provides a nice demonstration of the most common method I’ve seen used in pottery studios over the years. You might hear this technique referred to as the ‘rams head’ method. While the ideal clay wedging surface will be based on how a potter was trained, and individual preferences… this technique is broadly used.

Stack And Slam Method

This article is a great resource for those that want a wrist-friendly alternative to the Rams Head method. This stack-and-slam method is more similar to the way I was trained to wedge, back in the late 90s.

What Are The Best Clay Wedging Surfaces?

There are four main surfaces that Potters tend toward for this process: wood, canvas, stone and plaster. Which surface is best for your Pottery Studio is a matter of preference. The surface that works best for you will likely depend on the method you use, as well as the way you were training when you first learned to wedge.

Ideal Surfaces: What To Look For

The surface should be non-slippery. Smooth surfaces like stainless steel tables, for example, are far too smooth and will cause the clay to slip and slide around.

The surface should be somewhat porous. A porous surface will prevent the clay from sticking, and will help to remove excess moisture from wet and sticky clay.

The surface should be sturdy. The wedging process involves a lot of pressure, and sometimes slamming… so the surface should be sturdy and stay in place while you work.

I hope this information has been helpful as a general guide for wedging. If you’re ready to explore the various surfaces to choose from, find the most affordable clay wedging table set up, or need help selecting the best wedging board for your studio – we cover these topics in detail!
