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.
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.
In archaeology, a biofact (or ecofact) is any organic material including flora or fauna material found at an archaeological site that has not been technologically altered by humans yet still has cultural relevance. [1] Biofacts can include but are not limited to plants, seeds, pollen, animal bones, insects, fish bones and mollusks. [1]
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.

Example of a study skin Display with different examples of support forms. Traditional taxidermy specimens are cleaned and preserved animal skins that have been mounted over a form. [1] Full mounts are the entire specimen, while shoulder mounts only include the head, neck, and shoulders.
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.
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.
[10]: 176 Distinguishing different types of damage to animal bones is a tedious and complex process that requires background in multiple scientific fields. [10]: 169 Some of the physical damage on bones can be seen with the naked eye, but a lens with 10x magnification and good lighting is necessary for seeing most damage. [10]: 169
