Unique Copper Alloy Discovered in Sweden Get – History Blog

The Scandinavian pre-Roman pre-iron copper alloy got from Särdal on the west coast of Sweden is the first to be found in Sweden in 2022. Analysis of its composition found that it was also a metallurgical twin from metal hoards in Poland during the same period.

In fact, it was actually discovered when the Pedersen family dug a fenced cave in the garden. No other objects were found or were in nearby areas. They did not regard it as a prehistoric artifact and stored it in their workshop for five years until a family friend of an amateur historian suggested they show it to archaeologists at the Haaland Museum of Cultural History.

It is a flat-hole coin, a disc-shaped artifact with a flat top and a curved bottom is made by rotating the cast into a shallow mold or cavity on the ground. POG-shaped excavators, also known as BUN iNGOTS or cast cakes, have been found in both the Mediterranean and the European continent, and many examples have been found in shipwrecks during the Bronze Age and Iron Age.

Research shows that although Scandinavia is rich in copper ores, it was not mined during the Bronze Age. Instead, all copper is imported from far to southern Europe, and the trade volume is huge. Researchers estimate that large amounts of foreign copper are imported into Scandinavia every year until the third and second millennium BC as essential raw materials, and Ingots is an important source of information on how metals are remitted and traded from the Bronze Age.

Lead isotope and elemental analysis of copper alloy archaeological relics can determine the geographical origin and date of ore. SärdalIngot appeared, just like researchers at the University of Gothenburg. New investigations are being conducted on the use of the Bronze Age in western Sweden, and because the shape and size of the coin minting scrolls are typical of the Bronze Age fragments, they incorporated this unique finding into their study.

Surprisingly, analysis showed that the ingot was made up of copper, zinc, tin and lead alloys typical of the Iron Age. The sharing of information shared with Polish archaeological aluminum researchers led to another surprising discovery: Särdal Ingot discovered almost exactly the same metallurgical components in Poland between 2013 and 2015, both metal rods.

The copper source of all objects in the study, including särdaligot and Polish rod rubber, is a zinc-rich copper ore in southwestern Spain.

Iberia’s copper became the main source of ore in the late Bronze Age that had become the main source of ore in Scandinavia. The data of the subsequent Iron Age was not abundant, but during this period, Iberian mines were also strongly exploited. […]. Furthermore, since 1 millennium BC, seasonal alloys divided into all research materials are becoming increasingly common among all research materials. […]to a large extent, replaced the typical binary copper-tin alloy of the Bronze Age. Research in the Baltic region with close networks between Western Sweden and southern Scandinavia during the pre-Iron Age […]indicating that the Cu-Sn-Zn-PB alloys of the Särdal and Iława Lakeland types have been present in the second half of the 1st millennium BC. […]. We therefore propose that Plano-Convex Ingot from Halland and pole ingots from Poland can be considered both as ancient wild times used during the period corresponding to the pre-Roman pre-Iron Age of Scandinavia, which can both take into account the results of the maritime trade between the metal connecting Scandinavia and the Iberian Peninsula.
