Metals were discovered and developed independently in ancient South America. This resulted in a number of developments unique to various regions. Arsenical copper and tin bronze featured in some areas, but in many regions gilding, surface enrichment, depletion gilding and coloration were very important. This led to extremely thin gold coatings in what is now Peru and platinum coated gold in what is now present day Ecuador. Depletion gilding and silvering were commonly used in many cultures. Examples of the use of gold, copper, silver, and platinum in the creation of some of these alloys will be discussed with examples from the Moche culture of Peru to the Tairona culture of Northern Colombia.
