These graceful kinetic sculptures are wonderful to watch. The artist takes copper and swirls it into shape all while keeping a perfect edge/lip to catch the wind. He then uses a flame to create heat patterns in the finish. To keep these sculptures a shiny copper color, we recommend applying a clear lacquer periodically. Without lacquer, over time, these wind sculptures will turn a lovely patina green. They include a 12″ copper hook and attached swivel. Choose from three sizes or get one of each to create a dramatic effect. Other styles are available. We recommend a motor if displaying indoors (sold separately). Made in the USA!
