Abstract

A bronze mirror of Tang dynasty,were send to scientific analysis by three-dimensional microscopy,SEM-EDS and Raman spectrum analysis.The results indicated that:Ceruse,dolomite and crystal etc.were embedding in the bronze mirror;The gold plate and gold particle have high concentrations of silver (20%,Ag);The radius of these gold particle are different,which between 33.8~90.3 μm;The Raman spectrum analysis also indicated that,the green corrosion was Prussian blue.This indicated that the bronze mirror was a piece of Tang dynasty mirror that cover with gold leaf and embed with gemstones,but it was restored after 18 century AD.

Key words
