Ivory is a hard, white material from the tusks (traditionally from elephants) and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin, but ivory contains structures of mineralised collagen ...
Around 1160 northern European ivory carving was greatly reduced, which may well be because the material was less easily available. Around 1260, at the start of the Gothic period, elephant ivory began to reach Europe again, and the industry greatly increased. [4] The Norse also carved items in walrus ivory, notably the Lewis chessmen.
Ivory is a fragile medium; many 19th-century pieces were preserved because they were kept in a barrel of oil on board ship. Gary Kiracofe, a scrimshander in Nantucket, Massachusetts, advises collectors that if a piece looks dry, one should fill the center of the tooth with unscented baby oil and allow it to remain until as much oil as possible is soaked into the microscopic pores of the ivory.
An African elephant in Tanzania, with visible tusks. Tusks are elongated, continuously growing front teeth that protrude well beyond the mouth of certain mammal species. They are most commonly canine teeth, as with narwhals, chevrotains, musk deer, water deer, muntjac, pigs, peccaries, hippopotamuses and walruses, or, in the case of elephants, elongated incisors.
Engraved on the tooth is a picture of the ship Francis, which artist Fred Myrick served on during the early 1800s. Now, sperm whales are protected under the Marine Mammal Protection Act. So, in ...
The number of teeth and their function can vary widely between species, with some dolphins having over a hundred teeth in their jaws, while the narwhal has two functional teeth in its upper jaw which grow into long tusks in males. The tusk is used in feeding, navigation and mating and contains millions of sensory pathways, making it the most ...
Ivory is the tusks and unusually large or projected teeth of animals, such as elephants and walruses. It consists of dentin and made up of both organic (for growth and repair) and inorganic (rigidity and strength) components. Due to it being organic and inorganic the ivory is extremely sensitive and reactive [3]

Ivory carving is the carving of ivory, that is to say animal tooth or tusk, generally by using sharp cutting tools, either mechanically or manually. Objects carved in ivory are often called "ivories".
