Dr Sutherland and her colleagues from the Geological Survey of Canada-Ottawa and Peter H. Thompson Geological Consulting Ltd have now discovered that the interior of the vessel contains fragments of bronze as well as small spherules of glass.
The object, according to the scientists, is a crucible for melting bronze, likely in order to cast it into small tools or ornaments. Indigenous peoples of northern North America did not practice high-temperature metalworking.
