How does a touchstone on jewelry work?
toni35in2008 asked:
I need to know the physics behind how a jeweler can tell the authenticity of jewelry by using a touchstone. Can anyone explain this to me, even if you don’t know a whole lot about it?

In analyzing a jewelry we van use metallurgical assay. Metallurgical assay is analysis for metal and alloy. Assay methods are suitable for raw materials while others which are better suited for finished goods. Raw precious metals are assayed by an assay office. Silver is assayed by titration, gold by cupellation and platinum by inductively coupled plasma optical emission spectrometry. James
