Caucasian dagger blade made of arsenical bronze with 4.5 wt.% As; the hardness of the eutectic could be detected.

Finally, all samples are polished, so I can start with hardness measurements. Here, I would like to thank especially Fabrizio Barberis, DICCA,  and Armanda Barbangela, DIME, both Università degli Studi di Genova, for the possibility to carry out all hardness measurements with them. In that way, I was able to use both a purely mechanic, historic instrument, and could carry out also μHV measurements on my arsenical bronze alloys, as well as on Late Bronze Age daggers from Koban. The publication of the analyses of the daggers is currently in preparation, and will include chemical analyses, metallographic studies, hardness measurements, and Pb-isotope analyses.
