Master potter Richard Bresnahan wages a one-man campaign from his central Minnesota studio to tout the beauty and usefulness of clay pottery. Today in our Odd Jobs segment, we talk to the Collegeville potter who designed and built the nation's largest wood-fired kiln at Saint John's University, and the pottery studio on the edge of campus. Minnesota Public Radio's Laura McCallum visited Bresnahan in his earth-toned studio rich with the smell of indiginous clays, where he was starting his day preparing slip, the watery clay mixture vital for throwing good pots.
