Abstract

The characterisation by physical methods of the colour of gold alloys is of particular significance to industries which use them on account of their aesthetic qualities. In this article, the authors describe the systematic determination of the colour of alloys in the gold-silver-copper system. It embodies unpublished data which should be useful for future investigations.
