>
>
> Dear colleagues,
>
> I have recently analysed a group of 19-20th century Bulgarian silver
> jewellery. They appeared to have been made of Cu-Ag alloys with the
> surface being either depleted or mercury gilt. Most of these Cu-Ag
> alloys were found to contain 1-10 wt.% arsenic with one object
> containing even higher content.
>
> SEM-EDX analysis showed that arsenic is associated with copper. Based on
> the its variation in content, arsenic in these objects was probably from
> the copper ores instead of an intentional addition to the metals. Does
> anyone know any references on composition of Bulgarian copper ores?
>
> Any information would be appreciated.
