"Big data" is coming!

During November, CHARM has taken 300+ samples from medieval manuscripts and charters using a non-destructive eraser sampling method to find new insights into parchment production through . The technique involves gently rubbing the surface of the parchment to collect collagen fibres. This eraser waste is then analysed for peptide mass fingerprinting (PMF) through ZooMS (Zooarchaeology via Mass Spectrometry) to identify the animal species used to make the parchment. 

Never before have so many samples been taken in a research project on parchment. Bigger datasets will enable us to better understand historical trade routes, regional artistic practices, and the socio-economic conditions of the period. At the same time, CHARM establishes a comparative dataset for future research projects.

This work would not have been possible without the collaboration and support of the National Archives and the National Library of Finland - thank you!
