This twist of a marble is about 2 inches in size and shows yellow stripes dancing around the sphere. Yellow glass is pulled into rods of glass cane that are wrapped around green and blue glass, creating a spiral style. The sphere is finished by using a graphite mold to perfect the surface and shape of the marble.
