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.
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 also made of both mineral and carbon-based materials; the mineral-based are calcium, phosphorus, and fluoride; the carbon-based is the protein ossein. Bone also includes the mineral hydroxyapatite, "A calcium phosphate mineral which forms a hard outer covering over the collagen and protein matrix," [1] or organic material.
A reference collection of shinbones (Tibia) of different animal species helps determining old bones. Dutch Heritage Agency. One important aspect of zooarchaeology is using morphological and genetic evidence to answer questions zooarchaeologists have about the relationship between animals and humans. [7]: 172 These questions include:
Animal skin used for parchment all has the same basic structure, with slight variations due to the species, age and diet of the specific animal. Skin is composed of innumerable fibrils made up of the protein collagen , which are held in bundles that interweave in a three dimensional manner through the skin.

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.
