Get Your Pots into Shape with the Best Soft Rib Tools for Ceramics

Rib and scraper tools are essential for pottery and other ceramic work, aiding in the shaping and smoothing of clay. Though most often used when throwing pieces on a wheel, ribs can also be used in other clay practices. Ribs come in a range of hard and soft materials, but it’s the soft ones, traditionally made of rubber but now also of silicone or other polymers, that are best for removing fingerprints and imperfections when finishing pieces on the wheel. They can also be used for shaping or burnishing. There are more options than ever for soft, resilient rib tools for clay. Review our picks of the best ones, below.

2. Mudtools Polymer Rib

Mudtools was created by ceramicist Michael Sherrill, and the brand is known for innovation. While this rib looks much like other kidney-shaped ribs—and is in many ways—it is made from a proprietary polymer that is slightly sturdier than similar silicone options and more flexible than rubber. This rib is one step above the company’s softest polymer rib and offers plenty of versatility in the studio.
