Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged wood objects.
Water can come from roofs leaking during rainstorms, floods, fire sprinkler systems, or broken pipes. [7] It can soften and destroy the bone, antler, or horn if it becomes waterlogged. Mold and mildew growth can cause further damage. If the water in the crevices or pores of the bone, antler, or horn were to freeze, it would crack the object.
Most medium-sized animals (like dogs) are macerated within about ten days. Lipids and fatty acids in the bone and in the fat tissues tend to stain the bone brown. Oxidising bleaches may be used to whiten the bone, but if too much is used the perchlorate or hypochlorite damages the bone tissue, leaving it chalky and brittle. Hydrogen peroxide at ...
These methods will leave the feathers in good condition in their natural alignment. However, solvents may be needed to clean feathers if dust is held in place by grease, which can leach out of skins. Distilled water may be used if dry methods fail, but more stubborn dust may need to be cleaned with non-denatured 70% ethanol.
Instead, the needles were created from the bones of red foxes, bobcats, mountain lions, lynx, the now-extinct American cheetah, and hares or rabbits, the study found.
Bone is a material prone to cracks and splits during the dehydration process. If the bone has been established as weak and unstable, and that dehydration can cause cracks and splits to the bone structure, the bone is impregnated prior drying with the use of 50% solution of polyvinyl acetate (PVA(C 4 H 6 O 2) n) in distilled water.

The bones were found just feet (meters) from Jane's Carousel, a merry-go-round that was built in 1922 for an amusement park in Youngstown, Ohi Human bones found near carousel in waterfront park in ...
Cleaning of human remains varies by type. If necessary, surface cleaning of bone can be done with a very mild detergent and water solution, but bones should never be soaked in order to prevent dirt from becoming embedded in pores. [2] The possibility of cleaning human remains is highly dependent on the fragility of the specimen.
