Significance of Gold in Pre-Columbian Mesoamerica
It is believed that these types of pendants were made using the lost wax casting technique. In this process, the artists modeled the final piece they wanted to achieve in beeswax, and once the wax figure was finished it was covered in fine clay and charcoal, leaving pouring channels. The whole mold was then fired and the melted wax poured out. In its place, the molten metal cools and solidifies, and when the mould is broken, the final metal piece is finished and polished.
