The disclosure of Otto Meyer's secret : An evaluation of composition and casting properties of the Fritzi alloy

Sammanfattning: The increased copper price during the first world war forced the Swedish master founder OttoMeyer to invent a new alloy in order to continue casting artworks at a reasonable cost. The recipe of the alloy was a secret that Meyer kept to himself even unto death. The name of the alloy became Fritzi, but the number of objects cast in this alloy was never published.However, among the art pieces is G. Lindberg’s statuette “Vågen”. In this project, the composition of Fritzi was determined using SEM and EDS analysis on a sample from “Vågen”, and some thermodynamic, physical, and casting properties were evaluated usingsimulations and calculations. In addition to this, a 3D-replica of “Vågen” was created.
