Your Hands' Best Partner
Your hands are the primary tools for throwing, but they have limits. Fingers leave marks. Soft skin cannot apply pressure evenly over a wide area. Enter the rib: a simple, inexpensive tool that dramatically upgrades your throwing.
What Is a Rib?
A rib is a flat or curved tool used to shape, smooth, and compress clay on the wheel. Ribs come in several materials:
- Wood ribs: Gentle, flexible, good for smoothing and shaping soft curves. Great for beginners.
- Metal ribs: Firm and precise. Excellent for removing ridges and refining tight curves. Also used for scraping.
- Rubber/silicone ribs: Very flexible and gentle. Good for smoothing without removing much clay.
Each material feels very different in use. Most throwers own several types and choose based on the task.
What Can a Rib Do?
Shape: Press a curved rib against the outside of a bowl wall to push it into a specific profile.
Smooth: Drag a rib along the wall surface to remove finger ridges, leaving a clean, even surface.
Compress: Pressing a rib firmly against the clay aligns the surface particles: the same benefit as compressing with your fingers, but over a larger area.
Remove water: A flexible rib dragged up the inside wall pulls water upward and out of the pot, reducing the over-watering problem.
Rib Selection Shortcut
Use this simple mapping:
- Wood rib for gentle shaping
- Metal rib for crisp refinement
- Rubber rib for soft smoothing and moisture control
Choosing the right rib first prevents over-correction later.

Rib tools have been part of the potter's toolkit since the earliest days of the potter's wheel, and their function is closely related to how a lathe uses fixed tools against a spinning workpiece to achieve precise shapes. The studio pottery movement embraced ribs as essential companions to the hand, bridging the gap between craft intuition and mechanical precision.
