Several of the more ambitious disks juxtapose gilded and silvered copper sheet, and display images of great complexity. The joining of the gilded and silvered sheets is quite simple, and as is the case for the vast majority of objects attributed to Loma Negra the joins are mechanical, depending heavily on the use of tabs and slots. This simple joining method, however, was combined with a sophisticated use of metal color and surface treatment, and a scheme of spatial organization that, with the addition of movable components, convey a specific Moche, or perhaps even Loma Negra, aesthetic. Although these gilded and silvered copper disk ornaments are fashioned from dense, rigid and opaque materials they appear lightweight and animated.

This spatial organization, characterized by the layering of formal elements within a shallow three-dimensional space, is particularly apparent in the manufacture of the disk ornaments, which by their very nature have a clearly defined real plane that supports all of the superimposed layers. The small­est Loma Negra disk (diameter 15.5 cm), bearing a representation of the "decapitator" with outspread arms holding a knife and trophy head in each fist (1982.392.8) (fig. 8), can be used to illustrate this concept. In addition to dangles in three different sizes, this gilded and silvered copper assemblage consists of twelve components made from hammered sheet. The disk itself has only the simplest scored decoration that defines a band following the circurnference of the disk, and which is covered with large dangles. The decapitator, with his body and head in different levels of relief, fills the field demarcated within the disk (fig. 9). Details of his clothing are scored, while his chest is decorated with small dangles and his eyes, mouth and earflares are inlaid. In each hand he holds a curved knife, each a separate sheet with a narrow raised holder, while the trophy heads were attached in the manner of dangles. His "octopus" headdress is a flat sheet decorated with an owl head doubling as the staple that attaches the head­dress to his forehead. Four "rays" that emanate from his body are each made from a separate sheet with scored decoration and dangles.
