Cleaning tests: The paint surface is examined before and after treatment using light microscopy and VPSEM. The surfaces (right) have been treated with a 0.0822M solution of Citrate at pH 5.98 (equivalent to 2% w/v TAC).

The research within the department covers a wide variety of topics and disciplines within the field of the conservation of easel paintings including technical art history, conservation science and the development of conservation treatments.
