a non-specific alloy of gold and copper named by Spanish Conquistadors to metals composed of these elements found in widespread use in pre-Columbian Mesoamerica and South America. Many „golden“ masks are made from Tumbaga.
Depletion gilding is a method for producing a layer of nearly pure gold on an object made of gold alloy by removing the other metals from its surface. It is sometimes referred to as a „surface enrichment“ process.
