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.
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.
The deceased had a polished deer antler fitted on its head and two long pointed deer-bone rods across its throat. The deceased was found with various rare animal bone adornments, archaeologists said.
Bone, ivory, and antler are rarely attacked by insects, but horn is often seriously damaged by the larvae of carpet beetles and clothes moths. [7] Light, ultraviolet, and infrared. Ivory, bone, and antler should be kept away from bright light such as spotlights or direct sunlight. Bright light can increase the surface temperature of the object.
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.
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.
