Small Platter Polymer RibLong and lean, the Small Platter Rib is designed to give good compression when making plates and platters. It enables proper compression of the clay to avoid those cracks that sometimes develop. The Small Platter Rib is 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 our polymer ribs are made of a unique flexible materials, that are resistant to wear
