Form rings is a term used to describe the process of winding a material into a circular shape. This is often done with metal, such as steel or aluminum, and is accomplished by coiling the material around itself. The result is a series of concentric circles that can be used for a variety of purposes, such as creating jewelry or other decorative items. The term form rings is also used to describe the process of creating a mold from a material, such as clay or plastic, which is then filled with a liquid or other material to create a desired shape.
