Conservation-restoration of bone, horn, and antler objects involves the processes by which the deterioration of objects either containing or made from bone, horn, and antler is contained and prevented. Their use has been documented throughout history in many societal groups as these materials are durable, plentiful, versatile, and naturally ...
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.
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 ...
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.
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 site is important for many reasons, including the degree of preservation of ancient land surfaces, the impressive total extent of the palaeolandscape beyond the quarries (over 26 km wide), its huge quantity of well-preserved animal bones, its numerous flint artifacts, and its hominin fossils that are among some of the most ancient found yet in Europe.
Archaeological discoveries have unearthed older tools for tailoring, such as bone awls — which are simply sharpened animal bones found to have been used for cutting animal hides.
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]
