Ivory

Ivory is a hard, white material from the tusks and teeth of animals, that can be used in art or manufacturing. It 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. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, "ivory" can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed.

History

Ivory has been valued since ancient times in art or manufacturing for making a range of items from ivory carvings to false teeth, piano keys, fans, dominoes and joint tubes. Elephant ivory is the most important source, but ivory from mammoth, walrus, hippopotamus, camel, and narwhal, is also used.

Modern uses and concerns

In modern times, the high value of ivory has led to the poaching of elephants for their tusks, leading to a significant decline in elephant populations. This has led to many countries implementing bans on the trade of ivory.
