Reason for treatment
Examine, x-ray, clean, stabilize, repair, and repack as necessary.+
The knife is in good condition overall. It is complete, though the iron blade is heavily corroded. It has an uneven surface and has several raised blisters of orange-brown corrosion products. Some organic material remains both on the blade portion and the handle area, though it is largely mineralized.
The knife was examined under the microscope at up to 40 X magnification. The piece was cleaned manually under magnification using a scalpel to remove soil and corrosion products which were obscuring the surface. Care was taken not to disturb any organic remains, which were left in situ when found. The object was packed in a polyethylene bag and stored with silica gel as a dessicant ina sealed container, along with the other materials recovered from the same grave.The knife was subjected to Alkaline Sulphite treatment. 60 gr. Sodium Hydroxide mixed with 756 gr Sodium Sulphite in 3 litres of distilled water. The treatment was carried out for 6 weeks with the weekly changes in solution. The mineral preserved remains and the magnetite layer were intact, but fragile and changed colour.
Finds were discovered during the archaeological excavations before the Visitor Centre was constructed. The National trust donated all of the finds to the British Museum.
