Chair made by slaves from Ridgley Plantation near Florence, South Carolina. The chair is made with mortise and tenon joints reinforced with square nails. The seat is of animal skin. Evidence that the legs of the chair have been shortened indicates that it was a slave's chair. Slaves were not permitted to sit higher than the master or his children.
Large bolt found on top of the head of a hammer and an adjustable wrench in the bottom of the submarine interior. Images show an x-ray photograph of the bolt prior to deconcretion, the bolt with concretion, and the bolt following deconcretion and conservation treatment with subcritical fluid technology.
Wooden part of bench for supporting and holding forward and central sections of the submarine interior bench, with notch cut out to fit around the submarine interior frame. Images show the concreted bench support following excavation and removal from the submarine; reverse-side view of concreted bench support; x-ray photograph of bench support; bench support following deconcretion, conservation treatment with polyethylene glycol, and cleaning; the reverse-side view of the same post-deconcretion condition; bench support following freeze-drying; and the reverse-side view of the support post-freeze-drying. Note the holes in all images where nails or screws were once held to attach the support to the forward and central bench.
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.
Nut and bolt once connected to iron bar in between interior aft pump and horizontal rod support. Images show initial connection to iron bar in the submarine interior, x-ray photograph of the bolt and nut and the adjacent bolt, corrosion of the bolt and nut after removal from concretion, and bolt and nut after conservation treatment with subcritical fluid technology.
Metal suspender button loop and portion of chain made of silver. Images show concreted loop following removal from submarine interior and initial cleaning, loop following partial deconcretion by mechanical cleaning, and mostly deconcreted loop following mechanical cleaning with chain portion still partially concreted.
Clay smoking pipe bowl and stem, discovered in 2 pieces. Images show pipe in its original location within the submarine interior, stem and bowl pieces of the pipe following initial cleaning, and reconstructed pipe following conservation treatment.
Brass buckle with two prongs, possibly from a vest. Images show buckle following removal from the submarine interior with surrounding sediment and textile, and buckle following rinsing, cleaning, and thorough drying.
Brass thimble, 1.5 cm in diameter. Images show close-up of thimble following removal from the submarine and the thimble following mechanical cleaning and thorough drying.
Iron tool handle cast in a T-shape, with a square end. Images show the tool following removal from the submarine but prior to deconcretion, x-ray photograph of the tool, and the tool following deconcretion and conservation treatment with subcritical fluid technology.
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.
Wooden shelf from forward bulkhead in the submarine interior, found laying horizontal to the original upright orientation of the submarine. Possibly made of pine, approximately 1 inch thick, with cut-outs to fit in the bulkhead of the submarine. Images show wooden shelf within the submarine interior during excavation and wooden shelf after removal, conservation treatment with polyethylene glycol, and freeze drying. Note the rust stains on both ends where bolts had been used to secure the shelf.
Wooden plank used as a bench for crew operating the crankshaft, with notches carved out to fit around the frame ring supports. Images show the third section of the bench alongside the second bench section within the submarine prior to removal and the 3 different sections of the bench after cleaning, conservation treatment with polyethylene glycol, and freeze drying. Note also the carving in the front of one of the sections, which was done by a crew member to better operate the aft ballast pump.
Cast iron cover from the starboard deadlight with rubber seal on the inside, removed from hinge on interior of the hull plate. Images show x-ray photograph of deadlight cover, deconcreted cover with rubber seal in place, and cover with rubber seal removed after conservation treatment with subcritical fluid technology.
Silver suspenders/braces clasp belonging to Lieutenant George E. Dixon, discovered with the straps’ rubber elastic fragments attached. Images show the clasp following removal from the submarine interior with rubber fragments still attached, close-up of reverse side of clasp with concretion partially removed by mechanical cleaning, close-up of engraved initials reading "G.E.D." on front face of clasp following mechanical cleaning, and full view of front face of the clasp following mechanical cleaning.
Wooden object, possibly a bucket or small cask, made up of staves with a solid wooden end forming the bottom. Images show some staves and wooden end of bucket in its initial location within the submarine interior sediment, staves and wooden end of bucket laid out following initial cleaning, with some staves still concreted together, and staves of bucket reconstructed with velcro bindings following conservation treatment with polyethylene glycol and freeze drying treatment.
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.
Pencil composed of wood and coal, split into two halves. Images show the pencil pieces following its removal from the submarine interior sediment and pencil pieces following cleaning and freeze drying treatment.
