Abstract
The bucket described in this article, discovered 1951, Wiltshire, in a Saxon cemetery is of yew stave construction, waterlogged, with four broken and corroded bronze bands riveted in place. Dismantling prior to treatment is necessary. Corrosion products are electrolytically reduced in a 5 percent solution of sodium hydroxide, a sheet of iron acts as the cathode. Soaking in water removes residual chlorides. Fractured edges are soft soldered. Water in the wood is replaced by immersion in potash alum, glycerin, water (3-1-1) at 95 Celsius. After air-drying a surface coating of cellulose nitrate is applied. Reassembly is now possible. The missing bottom is replaced with plexiglass. Durofix adhesive holds staves in place during the assembly. This describes the treatment of a composite archaeological artifact by staff of the British Museum.
