One brilliant element was a series of ten minute presentations, one for each country involved (I gave the Irish one, all of the presentations answered the same research questions, you can see them in my powerpoint below), which gave a quick overview of iron technology and its place in society all over Europe and in lots of different time periods. These were also fleshed out in corresponding 2000 word summaries collated in the workshop handbook. Getting my hands on that alone was worth the trip to London! Luckily for everyone else it will be made available online soon too.
Hopefully the buzz from the workshop doesn't wear off now and the EU gives the convenors Peter Halkon and Vincent Serneels more money to kick-start iron research in Europe.
