In a new study, archaeologists analyzed iron artifacts spanning more than 400 years of American colonial history using X-ray fluorescence spectroscopy. Their results show that differences in the purity of iron and the trace elements it contains can be reliably used as a diagnostic feature to identify iron artifacts from different time periods.

Archaeologists from the University of Liège (Belgium) are conducting a new excavation campaign at the Palaeolithic site of Trou Al'Wesse in Modave. This exceptional site provides valuable information about the settlement of the first Homo sapiens populations in north-western Europe around 40,000 years ago. It is also an opportunity for archaeology students to gain practical experience in the field.

- Iron Age site believed to be potential ritual and ceremonial centre for community that also hosted large feasts

- Detailed laboratory examination and analysis of the fragile 2,400 year old cauldrons has revealed new information of their manufacture and long-term maintenance

- Results of the analysis have been used to create a full-sized replica cauldron

- A new display featuring the replica cauldron and story of the settlement will feature in Leicester’s newly opened Jewry Wall: A Real Roman Experience museum
