Pre-hispanic goldwork in the British Museum: some recent technological studies

Nigel Meeks

Resumen


Un examen tecnológico de orfebrería prehispánica suramericana de la colección del Museo Británico está llevándose a cabo actualmente. Usando microanálisis y microscopía electrónica de barrido se ha identificado una variedad de aleaciones y de técnicas de metalurgia antiguas usadas para producir un amplio rango de artefactos de oro. En este artículo se ilustra la investigación detallada de algunas fases binarias y de fundiciones ricas en cobre con superficies doradas. El análisis de anzuelos del río Cauca muestra el uso de un rango amplio de composiciones de aleaciones, desde oro argentífero aluvial hasta aleaciones de oro con alto contenido de cobre, tanto para alambres martillados como para artefactos fundidos. Se examinan en detalle, igualmente, las marcas dejadas por las herramientas sobre los objetos de oro.
