Handmade stoneware pottery by Susan Abromovitz of rock riffle run in Shade, Ohio. Rock Riffle Run Pottery is a boutique pottery — we lovingly make our pottery on a wheel (hand-thrown) and sign every piece, keeping alive an art form that is well over 3000 years old. Although we use some modern equipment today, the process and the materials remain much the same as they were in ancient times. It is a tradition that we are very proud to be a part of.
