This work presents a study of a pre-Hispanic artifact based on a reverse engineering methodology, by which an object is reconstructed by computer-aided design to obtain information. The object of the study is the Siecha raft–a Muisca goldwork piece that disappeared in the nineteenth century and was reconstructed based on historical sources. The pouring process of the raft was studied by characterizing the metal flow within a mold, by using the analytical, experimental, and computational fluidity length parameter. After this, the flow was studied, by using estimated parameters from the previous three methods, in the reconstructed geometry of the raft. Pouring temperature, materials, and temperature of the mold, entrance velocity, and other parameters of the fabrication process were calculated. The results showed that the geometry of the raft could have been cast by gravity casting pouring process, with the calculated parameters.
