    Reason for treatment


    Treatment proposal

    Stabilize chemically and physically. Clean, repair and support as necessary


    These objects were previously treated via consolidative electrolytic reduction (CER) as part of Treatments 5 and 6 in this event. They were separated from the other seals in Treatment 6 at the start of reduction in week 5 (22 -26 June 2009) prior to the copper contamination incident. At this point, the seals appeared to be furthest along in being reduced with only a few localised patches of white corrosion visible on the surfaces and so they were removed from the bath reduction process to undergo localised reduction.

    Treatment details

    Localised electrolytic reduction was applied to the objects using 10% sulfuric acid in deionised water as the electrolyte.

    The treatment was only partially completed. When not treating, the objects were placed into a bath of tap water. After a week, a white surface bloom formed on the object surfaces. These objects were then taken out of the water bath and solvent dried in an acetone bath.
