Eugene,
In fact, a complex question. Full table of bindings nobody was building. Theoretically, tehnikotehnologicheskim analysis for metals involved VNIIR - Dubrovin, as I told you and wrote. They have a few tables on the ligated elements. There is a laboratory in the Museum of Archeology, but it is not clear whether they have any data. But a serious examination of the metal and enamel nobody else does. Most likely, because it can be done only destructive method otkovyryat piece of enamel, rub it and determine the chemical composition, and in accordance with the tables, which in practice is not to determine when it may appear. We can try to determine the age, if the layer of varnish is a thin and pigments in the enamel will be those who will give the dating. Why such complexity, with all the DPI is much easier to refer to Gilodo Andrew Akimovich, you can reset the phone in lichku.
