An interesting paper, particularly the references to the electrum objects with a gold content of c. 67% and a silver content of c. 33%, which suggests the use of a standardised electrum composition in the 7th cent.
Presumably these are the objects referred to in paragraphs 17 & 18 in the paper by Melcher et al on the XRF analysis of the gold/electrum objects found at Ephesus.
However I couldn’t find these objects in Table 1 of Melcher et al’s paper, which is supposed to summarise all those results (you have to link on Table 1).
It doesn’t help that in the body of the Melcher paper these objects are referred to via their inventory number in the Ephesus museum (at Seljuk), but in Table ! a quite different numbering system is used.
And why does Table 1 mostly omit the silver content for the various objects?
