"The Archaeometallurgy of Iron" . "The paper presents the results of the metallographic and X-ray WD electron microprobe chemical analyses of the prehistoric hollow ring from the Bulls Rock cave. This Hallstatt hollow ring is dated to 600-500 BCE. The analyses resulted in the following coclusion: in the structure of a ring fragment, mostly of iron oxides, small quantity of copper oxides and traces of metallic copper and tin were found. The Hallstatt ring from the Bulls Rock cave was most probably forget of steel with a low carbon content. It was not either grey or white cast iron."@en . . . "190109" . "978-80-87365-41-0" .
