Metal file composed of wrought iron, initially found resting on top of a ballast block on the interior floor of the submarine. Images show the initial site of the iron file during excavation and the file after deconcretion and conservation treatment with subcritical fluid technology.
Rudder composed of wrought iron, discovered on the exterior of the submarine beneath the stern end with a large portion portside. Images show excavated rudder with concretion of coral growth and sea urchin spicules, rudder following partial deconcretion, deconcreted rudder treated in caustic solution, and fully deconcreted and cleaned rudder.
Hammer made of wood and wrought iron, found laying against adjustable pipe wrench in the bottom of the submarine interior. Images show the initial location of the hammer on the submarine interior hull, the hammer concretion together with the pipe wrench following removal from the submarine, x-ray photograph of the hammer following separation from wrench concretion, and the hammer following partial deconcretion.
Open ended wrought iron pipe wrench. Images show heavily concreted wrench in its initial location on top of ballast block, and wrench after cleaning, deconcretion and conservation treatment with subcritical fluid technology. Second image shows the extremely fragile condition of the wrench following conservation.
