What is Ivory?


Ivory is a hard, white material, derived from the tusks and teeth of animals, that is used in art or manufacturing.
It consists of dentine, a tissue that is similar to bone.
Elephant ivory has been the most important source, but ivory from many species including the hippopotamus, walrus, pig, sperm whale, and narwhal have been used throughout the years.
Ivory has many ornamental and practical uses. Prior to the introduction of plastics, it was used for billiard balls, piano keys, Scottish bagpipes, buttons and a wide range of ornamental items.
Synthetic substitutes for ivory have been developed. Plastics have been viewed by piano purists as an inferior ivory substitute on piano keys, although other recently developed materials more closely resemble the feel of real ivory.
A species of hard nut is gaining popularity as a replacement for ivory, although its size limits its usability.
It is sometimes called vegetable ivory, or tagua, and is the seed endosperm of the ivory nut palm commonly found in coastal rainforests of Ecuador, Peru and Colombia.
Since the 17th century, in Siberia, mammoth ivory has been carved, but has also been used to barter for other products.
Being a main center for mammoth ivory procurement, Siberian permafrost holds more than half of the extinct Woolly Mammoth carcasses that are the source of the milky white ivory that conforms to all international legal standards.
As ivory has the potential to be bleached, inlaid and carved, it has always been a highly prized raw material since man populated the Earth.
Humans took to expression in the form of paintings and carving, ivory has been the most preferred medium of expression. 
Art of carving ivory for ornamental or useful purposes, practiced from prehistoric to modern times. 
The ivory most frequently used is obtained from elephant tusks, but other types of ivory or substitute materials include the tusks, teeth, horns, and bones of the narwhal, walrus, and other animals, 
as well as vegetable ivory and synthetic ivories.
