Dear Dr. Maddin,
At the time being, I'm working on my doctoral thesis on "The Biginnings of
Bronze
matallurgy in Transylvania- Romania". A couple of weeks ago I had a debate with
some Romanian archaeologists who are unanimously stating that the raw material
used for the axes belonging to eneolithic cultures due to the high purity of
copper (99,3- 99,6 % Cu) it can't be but native copper. I made references to
your
paper, which you very kindly sent me two years ago ( Distinguishing artifacts
made of native copper- Jurnal of Archaeological Science 1980) in which you have
stated that the degree of purity cannot be used in the identification of native
copper.
Would you be so kind to advise me if there are any other analytical or
experimental studies dealing with this issue?! I would very much appreciate if
you could point me any references!
With my very best wishes,
Manuella Kadar
