I’m a consultant on Professor Padraig O’ Machain’s project ‘Inks and skins’ at University College Cork. Working alongside some of the most interesting people in insular manuscript research such as scribe Prof. Tim O’Neill and conservator of the Fadden More Psalter Dr. John Gillis this is a chance to get some theories thoroughly tested. The only downside is I need to start measuring things! You can follow the project here https://inksandskins.org/
