Sperm whales eject an intestinal slurry
called ambergris into the ocean, where the substance hardens as it
bobs along. Eventually it gets collected along shores - most often as sheer
happenstance, as in the case of eight-year-old Charlie Naysmith in the U.K. a few
days ago. Walking along the beach in Dorset
with his dad, the boy found what looked to be a very odd rock. He and his dad
used Google to help identify it as ambergris. Weighing more than a pound,
it is said to be worth up to U.S. $63,000.
The value of ambergris lies in its role in the fragrance
industry. High-end perfumes from houses such as Chanel and Lanvin take
advantage of the ability of ambergris to fix scent to human skin. The smell of
ambergris itself varies from piece to piece, ranging from earthy to musky to
sweet. If a perfume house's "nose" - the person responsible for
choosing scents - likes the aroma, the ambergris can be worth thousands an
ounce. Though it is illegal to use ambergris in perfumes in the U.S. because of
the sperm whale's endangered status, foreign markets, especially French, remain
strong.
Scientists still don't know for sure the exact origins of
ambergris. They do know that when sperm whales have a stomach or throat
irritant, often a squid beak, they cover it in a greasy substance and cast it
out. It was once thought the ambergris was ejected by mouth. As of now, the
argument seems to be weighted toward the back end of the whale.

Ambergris, (Latin: Ambra grisea, Ambre gris, ambergrease or grey
amber) is a solid, waxy, flammable substance of a dull grey or blackish color
produced in the digestive system of sperm whales. Freshly produced
ambergris has a marine, fecal odor. However, as it ages, it acquires
a sweet, earthy scent commonly likened to the fragrance of rubbing
alcohol without the vaporous chemical astringency. Although Ambergris
had been highly valued by perfumers as a fixative (allowing the scent to last
much longer), it has largely been replaced by synthetics.

Physical properties
Ambergris is found in lumps of various shapes and sizes,
weighing from 15 g (~½ oz) to 50 kg (110 pounds) or more.
When initially expelled by or removed from the whale, the fatty precursor of
ambergris is pale white in color (sometimes streaked with black), soft, with a
strong fecal smell. Following months to years of photodegradation and oxidation in
the ocean, this precursor gradually hardens, developing a dark grey or black
color, a crusty and waxy texture, and a peculiar odor that is at once sweet,
earthy, marine, and animalic. Its smell has been generally described as a
vastly richer and smoother version of isopropanol without its
stinging harshness. In this developed condition, ambergris has a specific
gravity ranging from 0.780 to 0.926. It melts at about 62 °C to a fatty,
yellow resinous liquid; and at 100 °C (212 °F) it is
volatilized into a white vapor. It is soluble in ether, and in volatile
and fixed oils.
Chemical properties
Applications
Ambergris has been mostly known for its use in creating
perfume and fragrance much like musk. Perfumes can still be found with
ambergris around the world. It is collected from remains found at sea and
on beaches, although its precursor originates from the sperm whale, which
is a vulnerable species. Ancient Egyptians burned ambergris as incense, while in
modern Egypt
ambergris is used for scenting cigarettes. The ancient Chinese called the
substance "dragon's spittle fragrance". During the Black
Death in Europe , people believed that
carrying a ball of ambergris could help prevent them from getting the plague.
This was because the fragrance covered the smell of the air which was believed
to be the cause of plague. This substance has also been used historically as a
flavouring for food, and some people consider it an aphrodisiac. During the
Middle Ages, Europeans used ambergris as a medication for headaches, colds,
epilepsy, and other ailments.
Legality
Many countries ban the trade of ambergris as part of a more
general ban on the hunting and exploitation of sperm whales.

In culture
* In chapter 91 of Herman Melville's Moby-Dick (1851),
Stubb, one of the mates of the Pequod, fools the captain of a French
whaler (Rose-bud) into abandoning the corpse of a sperm whale found floating in
the sea. His plan is to recover the corpse himself in hopes that it contains
ambergris. His hope proves well founded, and the Pequod's crew recovers a
valuable quantity of the substance. Melville devotes the following
chapter to a discussion of ambergris, with special attention to the irony that
"fine ladies and gentlemen should regale themselves with an essence found
in the inglorious bowels of a sick whale."
* In the 2001 film Hannibal , Hannibal
Lecter sends Clarice Starling a letter which he writes while intentionally
wearing a hand lotion containing ambergris, correctly assuming that this would
ultimately aid her in discovering his location in Florence , Italy ,
due to it being legal only in few parts of the world.
