When golden silver of ancient time comes up out of land, some surface layer contain copper to become rusty, especially silver-colored goods. Because golden silver is in,this kind of circumstance is before coming up out of land, had contacted the copper that other corrodes, if follow bury together with bronze ware, and was infected with cupreous rust. Another reason, it is the quality of a material of silver of archaic great majority, be in order to contain certain part copper alloy, after cupreous oxidation is corroded, formed cupreous rust overburden on silver. Do not pass this kind of case, can pass processing of the dirty that divide rust mostly, in order to recover from an illness the true colors of implements. In addition, experienced person, return the sound that can pass implements, flavour, and color, feel, will discern the true bogus of golden silver.

Nevertheless, this needs those who have long-term and rich practice experience to accumulate.
The differentiating of golden silver production time difficulty is great. The quality of a material to implements differentiates method of modern science and technology to already reached exacter level, differentiate to the time of implements however still appear helpless. Basically return be support experience to accumulate, and a when form on the foundation here scientific method that compares effective.


Say commonly, the take leave of of ancient bronze mirror of golden silver time does not open the research with inscriptive implements, also cannot leave to come up out of land the time of grave decides and make to implements form, the analytic research of the grain act the role ofing, technology that make. Compare under, the research with inscriptive implements is the directest, also be the most important basis. If be not had on golden silver inscriptive or inscriptions, to its production time is very difficult surely really.


Look from the development of Chinese gold silver, before Tang Dynasty on golden silver inscriptive very scarce. After Tang Yi, especially after Song Yuan, the golden silver that has inscriptive inscriptions is remarkable grow in quantity. Although do not have,some of gold silver goes up inscriptive, but what the other form that can adopt together companion to go out however makes the golden silver of close go up is inscriptive, have time secondhand illative. To coming up out of land the time of grave decides, have fundamental referenced value to breaking the period of deposit silver undoubtedly. But have inheritance sex as a result of golden silver itself, but years of all previous classics, acting acting according to legend. Consequently, of affirmatory gold silver make whether to belong to same age with the time that enter bury, still need other evidence to explain. The body that studies implements is made, grain act the role ofing, production technology and inscriptive wait for a feature, should saying is to use a the most extensive kind to conclude the method of the time of implements. Because of the implements of every times, contain the brand of that times inevitably, have the style feature with that times peculiar place.
