The analysis of the Book of Mulling has now been completed using the two techniques we have available in the Conservation Department, Raman spectroscopy and XRF. As posted before (see previous posts here and here) these are complementary techniques that together can help with the identification of pigments.

The use of colour in Early Irish Manuscripts can give clues about the resources available during the creation of the manuscripts, the skills of the illuminators, and the traditions of the community.
As we continue with our pigment analysis we have now commenced X-Ray fluorescence analysis of the illuminations and elaborated initials in our four manuscripts. This technique like Raman spectroscopy (see previous post) can, with the right equipment, be used in-situ directly on a manuscript without risk of damage, and similarly has a long history of use for the identification of pigments.1
