A fine tumbaga jewel
A fine tumbaga jewel
Colombia - Tairona culture
Lost wax copper and gold alloy cast.
The pendant probably represents a priest connected with the cult of Heisei, the mighty god of death and rain, depicted with a bat-like aspect.
The alloy used for this type of artefact, called 'tumbaga' contains up to 75% of copper in it and consequently a small quantity of gold. To give a shiny appearance similar to pure gold was used the depletion gilding method: removing the copper from the surface with the aid of acids or salt and then burnishing the surface to make it smooth and shiny the craftsman produces a superficial nearly pure gold layer.
