Mystery Pot 16! The maker of this pot is Walter Keeler, known internationally for pushing the envelope with his functional ceramic work. His influences are many including Greek and Roman forms and industrial shapes such as oil cans and milk churns. Walter Keeler created a British renaissance for salt-glazed ware in the 1970s. In recent years, he has been working with earthenware making fabulous, brightly glazed, otherworldly forms with extensions that look like branches or pieces of valves.
