Subject: Gums
The following is posted on behalf of Bronwyn Ormsby I am a Painting Conservator currently studying for a Ph.D. at the University of Northumbria at Newcastle. My research is a collaborative project between the University and the Tate Gallery in London. Dr. Brian Singer of the University of Northumbria and Dr. Joyce Townsend of the Tate Gallery are two of my supervisors. The title of the project is "An investigation into the materials and techniques of William Blake (1757-1827) and his followers"--with a focus (at least initially) on his tempera paintings. The project aims to thoroughly document Blake's techniques and involves a literature search into his use of materials as well as into the availability of water-colour paints, gums and proteins during the late 18th and early 19th centuries. The second part of the research involves scientific analysis of media via the use of Gas Chromatography-Mass Spectrometry (GC-MS) and High Performance Liquid Chromatography (HPLC). I am beginning the analysis with a survey of gums traditionally used as paint media, and have gathered samples from as many sources as possible. The next stage is the analysis of water-colour paints and artists palettes from the time period. After this, I will begin analysis of Blake paintings, primarily from the Tate collection and ultimately also from other collections. I am wondering whether anyone can help me with information regarding gums and water-colour paints used until about 1850 in England. I am also interested in obtaining samples of water colour paints produced in the first half of the 19th C and late 18th C and am interested to sample any archival material. I would very much appreciate any advice, information and/or samples people can offer. Of course, I will include acknowledgements in my thesis and any papers arising from the research.
