An international team of Serbian and UK researchers claim to have developed a Cu-As-Sn (Copper-Arsenic-Tin) color ternary diagram, which will help scientists to uncover the original colors of ancient artifacts now patinated through age and exposure. Evolutionary Copper-Arsenic-Tin Color Ternary Diagram Developed Despite various studies of ancient gold metallurgy being fully supported by modern research in color characteristics of gold alloys, the color properties of major prehistoric copper alloys, such as arsenical copper and tin bronzes, have remained vastly understudied as they are not easily accessible to the western scholarship. That is about to change, however. As Phys Org reports, a new study conducted by an international team of Serbian and UK researchers and published in the Journal of Archaeological
