A flame color-enhancing apparatus includes a hollow outer tubular member having a predetermined copper content, a predetermined inside diameter and surface, and a first predetermined length; and an internal tubular member frictionally disposed within the outer tubular member to a predetermined ratio of contact of the interior surface of the outer member to exterior surface of the internal tubular member. The internal tubular member contains a predetermined content of chlorine-based polymer and has a second predetermined length and an outside diameter substantially equal to the predetermined inside diameter.
