These bird bowls are hand-cast in solid brass from clay models made by our pottery team in our Soho studio. Style them together for a clustered masterpiece or on their own for a twinkly sculptural statement. Like a fine wine or your favorite leather jacket, our brass only gets better with age. Over time, the polished brass will develop a rich natural patina. If desired, use a microfiber cloth to buff out fingerprints. If you have no patience for patina, use a brass polish
