Long and lean, theLargePlatter Ribisdesigned to give good compression when you are making plates and platters enabling you to properly compress the clay and avoid those cracks that sometimes develop. They are made with a stiff polymer, but still offer some flexibility.All of our polymer ribs are made of a unique material, which is resistant to cracking and the formation of burrs.Weve found that with general use this rib material becomes burnished over time.Each polymer rib shape is available in a variety of hardnesses.Whether you are 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 potters hand to create shapes and surfaces that fingers alone can not achieve. We believe our tools should not only function well, but should be pleasant to look at and a joy to use. Whatever you want to make, weve got you covered.
