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 ...
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.

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.
The discovery of Stone Age needles made from the bones of foxes, cats and other small carnivores reveal how prehistoric humans survived in cold climes. Archaeologists discover key tool that helped ...
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]
Treatments should be carried out by conservators or qualified taxidermists. Some taxidermists have experience working with museums and can coordinate with conservators to preserve specimens. When cleaning specimens, it is necessary to wear protective gear such as nitrile gloves, dust masks, eye protection, and lab coats.
Add aromatics (like roughly chopped celery, carrots, and onions); spices (like black peppercorns); and herbs (like thyme and parsley); and cover with water to submerge. Bring liquid to a boil over ...
