Résumé

A thorough analysis of three votive gold figurines from the collection of the Musée du Quai Branly in Paris reveals the composition of the alloys and the manufacturing techniques used.
Paz Nunez-Regueiro, heritage curator, talks about the origin of these objects belonging to the Muisca culture (600 - 1600 AD) of Colombia.
Maria Filomena Guerra, research director at the CNRS, explains the methods used: binocular magnifying, scanning electron microscope analysis which evidence the use of the lost wax casting technique, use of the Aglaé particle accelerator to determine the composition of alloys and X-ray radiography.
