Removal of incorrect number and reapplication of correct number. Removal of corrosion products.
The object is in fair condition overall. The surface is degraded with a porous surface. There are some holes on the edges of the cross. Where the lead cross has been bent the metal is thin and vulnerable. There are white lead carbonate corrosion products obscuring the surface.
The lead cross was immersed in Acetone (propan-1-one/dimethyl ketone)to remove any surface coatings and/or grease.Stabilized by consolidative electrolytic reduction in a 10% aqueous solution of sodium carbonate electrolyte using stainless steel anodes, for 6 hours. Deposit from reduction removed by brushing in running tap water with a stiff hog hair brush.Not all the lead corrosion products were reduced so it was further stabilised by local reduction using a 10% aqueous sodium carbonate electrolyte on cotton wool swabs with a graphite anode, for 2 hours. Washed with tap water for 24 hours. Dried with Industrial methylated spirits (ethanol, methanol) on cotton wool swabs. Consolidated using 10% HMG Paraloid B72 (methyl ethyl methacrlylate) in Acetone.Renumbered with the correct number using magic ink applied with a brush.
Found with about 100 others and 400 bodies.
