Micro-raman spectroscopy of decorated pottery of the diaguita culture from iv region, chile (9th-15th century ad)

Abstract

Raman spectroscopy pigments on decorated antique Chilean pottery belonging to the Diaguita's culture deposited in Museum of Limarí, have been studied by using Raman spectroscopy. Four ceramic fragments from the unknown contexts were examined. Four colors were found with certainty: red, black, brown and white. Quartz and manganese (kempite) salts, as well as different types of oxide pigments: hematite, tenorite and possibly goethite, were identified.
