It has a red-orange color that oxidizes over time turning the surface a darker brown, blue, or greenish color depending on the environment. Each copper part is 3D printed in a wax material which is used to create a mold for investment casting. Lost wax casting is capable of showcasing intricate details, offering a professional, finished look and feel that oxidizes over time creating a corrosion resistant boundary layer on the surface of the part. Internal detail can not be polished, well-reachable surfaces will be polished therefore tight internal spaces may remain unpolished.
