Questions that Lead to More Questions

I joined the Conservation Department at the IMA in October as Assistant Conservator of Objects and Variable Art.  One of my most exciting projects to date has been the examination of the Corner Cabinet with Breton Scenes by Emile Bernard, a rare example of Pont-Aven School wood carving acquired by the IMA in 2010.

Laura Kubick, Assistant Conservator of Objects and Variable Art and Jeff Fieberg, Associate Professor of Chemistry at Centre College, analyzing the cabinet in the gallery using XRF.

My work has focused on the surfaces of the cabinet. To discover what pigments might be present, I first used XRF with the help of Jeff Fieberg.  Some pigments suggested by this work are red lead, chrome yellow and ultramarine blue.  I am also trying to find out what type of paint is present – is it oil, tempera, distemper, etc.?  And is there a coating layer over the paint?

Microscopic examination revealed wax on the surface. I also took microscopic samples that will be analyzed using Fourier Transform Infrared Spectroscopy (FTIR) and Raman Spectroscopy with the help of Greg Smith, the IMA’s Conservation Scientist. These techniques will tell us which type of binder the paint has and more definitively identify the pigments present.

Once we have those answers,  I will work with Ellen Lee, The Wood-Pulliam Senior Curator, to answer further questions like would the cabinet benefit from cleaning and can cleaning be undertaken safely?  We may also answer a question about whether the frieze panel with faces is original to the cabinet or whether it may have been added later.  The work that Lee, Richard McCoy, and Jérôme Séré completed in the fall of 2010 examining the structure of the cabinet (check out the blog about this work) suggested that this may have been the case.  I look forward to the results of the analysis and sharing more about the cabinet.
