Many hands, one culture

Variations in technique and style among the Quimbaya gold artifacts suggest multiple artisans were involved in their creation.

Quimbaya artisans, both men and women, mastered the techniques of metal casting and lost wax. They were able to create works of great beauty and uniqueness, such as this figure of a seated chief.

Lost wax casting

To produce the objects, an initial core was made from a mixture of clay and charcoal, which was covered with wax and modelled. This was then covered with another layer of clay, and when the wax in between had melted, it was replaced with molten metal.

Removing the outer and inner clay and polishing the piece is the final stage. On these earrings it is clear that there has been no removal of the inner core, so the earrings should not have been in use.

Partitioning and repair

To prevent movement between the inner and outer clay cores, connecting partitions were placed after the wax layer had melted. These partitions left rounded holes which were later covered with a metal plate and polished.

Notice the cast partition plugs on the figure's skull and buttocks. A repair is also visible on its back. These details reveal the artisan's process.

Added components, as seen in this vessel's X-ray, weren't always fully integrated into the Quimbaya artifacts, often becoming detached.

Other techniques: Casting, hammering and embossing

Some of the pieces, such as the helmets, after the lost wax casting, had their decoration finished by hammering on a certain shape. This way, semi-spherical reliefs, dots, lines, etc. were obtained.

This helmet shows Quimbaya's intricate techniques: relief work from the back, outlining from the front, and detailed incised lines visible at the base.

Additions

Some Quimbaya pieces used a tongue-and-groove system for added elements. This female figure's head, for example, was attached to the helmet after the initial casting.

The embossed body contrasts with the separately added head, which originally featured lost inlaid stone or shell. This reveals the artifact's layered creation.

Casting errors: Technical expertise

Sometimes, due to a technical fault in some part of the process, for example, if the temperature of the metal did not reach the necessary melting point, the entire space left by the wax was not filled, causing gaps such as those seen in the vessel.

To cover them, a second casting was usually made by filling in the losses with wax and re-melting that part, but these additions were easily lost, as happened in this case.

Colors of alloys

By successive casting (first the parts with metals or alloys with higher melting points and then alloys with lower melting points), pieces of different colors were made, such as this stick for consuming lime.

This lime stick features a bird with copper-colored wings and crest, and a gold body. Gold, having the highest melting point, was likely cast first.

By applying oxalic acid and polishing, goldsmiths could selectively remove copper, revealing the underlying metal and creating varied colors on the same piece.

This has resulted in areas, such as the gold outer surface of this disc-shaped pendant, where the copper has been removed. The inside, however, still shows the copper color.
