The Large Platter Rib and Small Platter Rib enable proper compression of the clay to avoid those cracks that sometimes develop. They are made with a stiff polymer, but still offers some flexibility.
The Small Platter Rib is particularly useful in making shallow pasta-style bowls.
All of Mudtool's polymer ribs are made of unique flexible materials that are resistant to wear and the formation of burrs. With general use these ribs become burnished over time.
Whether throwing clay on the wheel, hand-building or sculpting, the pottery rib is a classic and essential tool. It acts as an extension of the potter's hand to create shapes and surfaces that fingers alone can't achieve.
