Decorative element resting on the surface of a sculpture, using a variety of attachment methods including solder, adhesives, cements, and/or rivets. Overlay materials may include a range of materials among them metals, glass, stone, bone.
Note: The terms “inlay” and “overlay” are often used indiscriminately, although they differ in one main regard: inlays are inserted into the bronze surface whereas overlays are set onto the surface.
