# The Spiral Wedge

Spiral wedging is a rhythmic, efficient technique popular with production potters. Once you get the rhythm, you can wedge large amounts of clay quickly without tiring your wrists.

## The Setup

You need a sturdy wedging table at roughly hip height. Canvas stretched over the surface is ideal: it grips the clay and is easy to clean. Stand close to the table so you can use your body weight, not just your arm strength.

## Hand Position

Place the clay in front of you. Rest both hands on top of it:

*   **Dominant hand** (right for most people): this is your pushing hand. Place the heel of your hand on the upper-right portion of the clay.
*   **Non-dominant hand**: this is your guide hand. Place it on the left side of the clay, slightly lower.

## The Three-Part Motion

Every repetition has three beats:

1.  **Push**: Lean your body forward and press the heel of your dominant hand down and away from you into the clay.
2.  **Rotate**: As you release, your guide hand nudges the clay slightly clockwise (or counter-clockwise if left-handed).
3.  **Reset**: Rock back and lift slightly, returning your hands to the starting position.

Repeat (push, rotate, reset) over and over. After a dozen repetitions you should see the clay taking on a cone shape with a spiral pattern forming on the nose.

## The Shape to Aim For

A well-executed spiral wedge produces a conical lump with a tight, shell-like spiral on the side. That spiral pattern is visual proof the clay is being folded and worked from the inside out.

## 3-Step Practice Progression

Build skill in short rounds:

*   **Round 1 (500g clay)**: focus only on push, rotate, reset rhythm.
*   **Round 2 (same weight)**: keep cone shape consistent for 30 strokes.
*   **Round 3 (750g clay)**: maintain form while increasing force from body weight.

If form collapses, drop back to the previous round and repeat.

## The Bigger Picture

The spiral pattern you create is a real-world example of a [logarithmic spiral](https://en.wikipedia.org/wiki/Logarithmic_spiral), the same shape found in nautilus shells and galaxies. Japanese potters call this technique *kikumomi* (chrysanthemum wedging) because the spiral resembles a [chrysanthemum](https://en.wikipedia.org/wiki/Chrysanthemum) flower. Production potters in the [Mashiko](https://en.wikipedia.org/wiki/Mashiko,_Tochigi) tradition can spiral-wedge 20kg of clay in minutes using this exact rhythm.

## Check your understanding

### Question 1: In spiral wedging, what does the guide hand do?

- [ ] A. It pushes the clay forward
- [x] B. It rotates the clay slightly with each stroke
- [ ] C. It holds the clay still
- [ ] D. It adds water to the clay

Tip: The guide hand rotates the clay slightly between each push to create the spiral pattern.

### Question 2: What part of your hand should you use to push the clay?

- [ ] A. Your fingertips
- [x] B. The heel of your hand
- [ ] C. Your knuckles
- [ ] D. Your thumb

Tip: The heel of the hand (the fleshy base near the wrist) generates the most force without straining the fingers or joints.

### Question 3: What is the best cue that your spiral wedging rhythm is working?

- [ ] A. The clay becomes flatter each stroke
- [x] B. A cone forms with a tight spiral pattern
- [ ] C. The guide hand stays completely still
- [ ] D. You hear air popping in the clay

Tip: A controlled cone shape with a tight spiral pattern shows that push, rotate, and reset are working together.
