| Popis: | Three iron padlocks have been recovered from the shipwreck site of HMS Pandora. In 1791, the 24-gun frigate was lost after striking the Great Barrier Reef, the crew having recently searched a number of Pacific islands and captured 14 mutineers from HMAV Bounty. Typically, in the marine environment, the iron padlocks had become encapsulated in concretion, a cement-like material derived from a combination of iron corrosion products and seabed materials. One of the three padlocks (P535) was conserved at the Western Australian Museum’s Department of Materials Conservation. This paper describes the considerations made and steps taken to ensure the best outcome for what proved to be a largely intact but badly degraded object. The treatment process selected was hydrogen reduction, followed by soaking in a corrosion-inhibiting sodium hydroxide solution (2%) to permit release and monitoring of chlorides. In addition to the conclusions drawn about the conservation of the padlock, a speculative conclusion is... |
