In April 2015, prior to the project’s official start, I was already able to present my ArsenicLoss project ideas and work plan at the ‘Glass and Metal Recycling in Archaeology and Archaeometry’ workshop at the University of Leicester, UK. The workshop was kindly organised by A. Cuénod and C.N. Duckworth (a warm thank you to both for everything!) in the frame of the ERC-funded Trans-Sahara project. This workshop and the associated discussion possibilities provided valuable hints for the experimental set-up and laid the groundwork for cooperation with other colleagues.
