It has long been known that an alloy of silver and copper is not satisfactory material for the trial plates which are used in testing the fineness of the Imperial silver coin and of silver wares before they ar hall-marked. As long ago as the year 1580 the lack of homogeneity of silver-copper alloys was well known to the German metallurgists, and in 1852 Levol concluded that the only uniform alloy of the series contained 718.93 parts of silver and 281.07 parts of copper a composition which corresponds to the formula Ag 3 Cu 2 .

It is a well known fact that when molten alloys of certain metals are cooled, some of the constituents separate and become concentrated either in the centre or in the external portions of the solidified mass; to this segregation the name of liquation is given. It is specially noticeable in the case of silver-copper alloys, and its importance is now being widely recognised in almost all branches of metallurgy. In the case of gold, however, the phenomenon of liquation does not appear to have been much observed. Gold alloys, to the value of many millions sterling, pass annually from hand to hand upon the results of assays cut from the external portions of ingots, which assays cannot, of course, be trustworthy, if the centre of the bars differs in composition from the external portions. Peligot has recently endeavoured to obtain evidence of liquation in gold-copper alloys, and has concluded that it does not exist. Roberts-Austen, who has devoted much time to the study of liquation, has also satisfied himself that gold-silver alloys do not rearrange themselves on cooling.
