Results. It is generally recognized that lead should be introduced through copper ores if the lead content is below 2%. By contrast, when the lead content of ancient bronze is higher than 2%, lead is purposely added using lead ores (Liversage 2000).As shown in Table 3, the samples' lead concentrations are all higher than 2%, which …

Isotopic investigations of Chinese ceramics
Thus, lead isotope ratios are used in archaeological chemistry to trace lead-containing artefacts back to their ore source (Gale and Stos-Gale 2000; Pollard et al. 2006). So far, lead isotope analysis is the most effective method for the provenance study of lead-bearing objects such as metals, lead-silica glass and lead glazed ceramics.
Lead isotope analysis for provenancing ancient …
The ore database used in this study to compare artefacts to ores and mining regions was compiled from the literature. The database used by De Ceuster and Degryse2 was supplemented with additional data, now counting 200 mining regions and a total of 3640 lead ore samples.14 For each ore sample the three fundamental ratios measured in …
Native North Americans Were Making Copper Tools in …
Re-dating of old discoveries and more refined dating of new ones have pushed the starting date of the Old Copper Culture back much farther, to the year 7,500 BC. The use of copper tools among Native Americans who built this culture peaked between 5,000 BC and 3,000 BC, before declining precipitously after that.

Earliest Lead Artifact in World Found in Israeli Cave
A large lead bead-like object with a stick through it, dating back 6,000 years, was discovered deep in a cave by archaeologists in Israel – but analysis of the metal indicates that it came from southern Turkey, revealing that either the lead ore or the object had been imported.

Tracing Roman lead sources using lead isotope analyses in
In antiquity, lead played an important role both for the military and general public. Building construction, in particular, consumed large amounts of this metal. Nevertheless, the supply sources for lead during the Roman Imperial period have not been satisfactorily accounted for. The following paper aims to clarify the provenance of lead …
How ancient Rome poisoned not only itself but Europe's air with lead
But the lead came from Turkey – the Taurus range in Anatolia. So even if the earliest lead artifact was found in Israel, in Ashalim Cave, either the ore was imported, or the bead was made in Turkey.Even so, according to Naama Yahalom-Mack and the team, the ancient world had little use for lead except to weigh down fishing nets, as described …

The Provenance, Use, and Circulation of Metals in the
The use of lead isotope (LI) data in archaeology relies on the unique property of lead to be characterized by its isotope abundance ratios in an ore deposit (Gale and Stos-Gale 2000), which is associated with the average terrestrial "ore-lead" at the time of mineralization (Loveless 1975). Since three of the four lead isotopes continuously ...
