Production of arsenical bronze using speiss on the Elephantine Island (Aswan, Egypt) during the Middle Kingdom (Middle Bronze Age) (c.2000–1650 BCE)

open access: yesArchaeometry, Volume 68, Issue S1, Page S38-S63, April 2026.
Abstract This paper presents the first direct evidence of the slags produced during the cementation alloying process of Cu with speiss inside ceramic crucibles, thus representing Cu alloying with As in Middle Kingdom Egypt. The settlement deposits from the Middle Bronze Age were excavated on Elephantine Island, within modern Aswan.
