This was one of the experiments we undertook to verify the data before publishing the results.
We wanted to check the ironwork because, during the course of the project, it has gradually become clear that the iron was being re-processed around the area. Because this has never been positively identified around any other battle from this era, it was important to find out as much as possible as the bits and pieces.
We could not be sure what we would find: the results have helped to confirm the working hypothesis that this was post-battle metal-recycling. But the XRF data has provided an insight that will take some time to understand.
What is X Ray Fluorescence?
This clever device shines xrays at the surface and records what bounces back. (This is like shining a special torch but you would need x-ray eyes to see the reflection). Oxford Instruments very kindly brought their handheld XRF machine to the York so that we could examine some of the ferrous material we had gathered.
It will take time to analyse all the data produced.
The key finding is that the items tested are all pre-industrial (apart from a few test pieces that were slipped into the mix as controls).
A very big thank-you to Oxford Instruments for all their help (This was the second time they have helped on the Fulford project).
And to the staff and students at the Department of Archaeology at the University of York for accommodating and working round us.
Without the assistance and guidance of so many people during this project, we could not have achieved such an insight into our past.
