Best Pottery Ribs: Wood, Metal, and Silicone Ribs Compared
Updated How we research
A rib is the simplest tool at the wheel and one of the hardest working. It compresses rims, pulls clean curves, smooths slip off the surface, and shapes profiles your fingers cannot hold steady. The material matters more than beginners expect: wood ribs flex gently and suit soft clay, metal ribs scrape surfaces glassy smooth, and silicone ribs polish without leaving tool marks. Most potters end up with a small stack in every shape, but a few well-chosen ribs cover nearly everything. This guide rounds up the pottery ribs we rate highest, explains where each material and profile earns its place, and suggests a starter set that will not gather dust.
