Anthropology professor Francis Allard and undergraduate student Jacob Ulmer spent one week in Vietnam studying metal objects dating to the region’s Bronze Age.
A part of the broader “Bronze Age of Northern Vietnam” project, this research trip involved using pXRF (Portable X-ray Fluorescence) equipment to determine the alloy composition (copper, tin, arsenic, and lead contents) of 25 bronze objects dating to
the first millennium BCE in northern Vietnam. Allard’s team also met with geologists to develop a future project aimed at locating the sources of ores used in the production of bronze artifacts.
