A white pigment found on a sub-set of polychromed wooden Andean ritual drinking cups called qeros has been characterized by X-ray diffraction, fluorescence spectroscopy and Raman as consisting principally cristobalite (SiO2), anatase (TiO2), α-quartz (SiO2). This unexpected assemblage minerals is like that reportedly in an exposed titanium ore body southern Peru, area once part the Inka Empire. The close match color composition to offers possible candidate for geological source this...
Abstract
Abstract For millennia, qeros have been a primary component of ceremonially and politically important toasting rituals in the Andes retain their cultural significance to this day. These wooden drinking vessels underwent stylistic technical revolution colonial period (1532–1821 AD). Among an array features that distinguish from Inka predecessors is presence lead white, pigment was introduced by Spanish. Here, we present (Pb) isotope measurements white pigments 20 collections National Museum...
Microscopic examination and analysis (metallography, X-radiography, SEM–EDS, pXRF μ-XRF) of a group stylistically linked gold alloy pendants from western north-western Colombia confirms the use highly unusual manufacturing technique for region. While Darién were made using lost-wax casting by diverse cultures southern through Costa Rica, only one subset produced in Gran-Zenú region (the Caribbean lowlands northern Colombia) Chocó Pacific area Early Period (ad 0–900) was found to be...
