Reason for treatment
Examine, x-ray, clean, repair, stabilise, and re-pack as required.
The knife is in good condition overall. It is complete but is in four fragments. The iron blade is corroded and has an uneven surface with raised blisters of orange/brown corrosion products. The surface is covered with sandy soil. The organic remains upon the surface are largely mineralised.
The object was examined under the microscope at up to x100 magnification. The blade was cleaned both manually using a scalpel, and mechanically with the air-abrasive using Aluminium oxide, No1 powder. This removed the soil and the iron corrosion products that were obscuring the surface. All mineralised organic remains were left in situ. The knife was rejoined using HMG adhesive (cellulose nitrate). The surface of the iron was consolidated using 3% Paraloid B72 (ethyl methacrylate copolymer) in 50:50 Industrial methylated spirits (ethanol,methanol) and Acetone (propan-1-one/dimethyl ketone). The object was packed in plastazote in a crystal box and stored with silica gel as a desicant in a sealed stewart box.
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.
