The identification of the ship led to high public interest in the salvage operation and caused a great demand for the objects that were brought up. Though many of the objects could not be properly conserved at the time and subsequently deteriorated, many were documented with pencil sketches and watercolour drawings, which survive to this day. John Deane ceased working on the wreck in 1836, but returned in 1840 with new, more destructive methods. With the help of condemned bomb shells filled with gunpowder acquired from the Ordnance Board, he blasted his way into parts of the wreck. Fragments of bombs and traces of blasting craters were found during the modern excavations, but there was no evidence that Deane managed to penetrate the hard layer that had sealed off the Tudor levels. Deane reported retrieving a bilge pump and the lower part of the main mast, both of which would have been located inside the ship. The recovery of small wooden objects like longbows suggests that Deane did manage to penetrate the Tudor levels at some point, though this has been disputed by the excavation project leader Margaret Rule. Newspaper reports on Deane's diving operations in October 1840 report that the ship was clinker built, but since the sterncastle is the only part of the ship with this feature, an alternative explanation has been suggested: Deane did not penetrate the hard shelly layer that covered most of the ship, but managed only to get into remains of the sterncastle that today no longer exist. Despite the rough handling by Deane, the Mary Rose escaped the wholesale destruction by giant rakes and explosives that was the fate of other wrecks in the Solent (such as ).For a detailed account of the Deanes see John Bevan, The Infernal Diver: the lives of John and Charles Deane, their invention of the diving helmet, and its first application to salvage, treasure hunting, civil engineering and military uses.
