Ambergris (Geological/Organic Specimen)

Physical Properties

Waxy texture, brownish-gray to black color, earthy/sweet/fecal odor that sweetens over time, density less than water (floats), melting point of about 62°C (144°F), soluble in ether and oils.

Formation & Geological History

Formed in the digestive system of sperm whales as a secretion to coat sharp objects like squid beaks. It is expelled and floats in the ocean, undergoing years of oxidation and photodegradation by sunlight and seawater.

Uses & Applications

Primarily used in high-end perfumery as a fixative to make scents last longer. Also historically used in traditional medicine and food flavoring.

Geological Facts

Often called 'floating gold' due to its rarity and high value. It starts as a foul-smelling black substance but matures into a light gray substance with a complex, pleasant aroma over decades at sea.

Field Identification & Locations

Identify in the field by checking if it floats, applying a hot needle (it should melt into a dark, waxy liquid and release a characteristic smoke), and its unique smell. Commonly found on coastlines in the Atlantic and Pacific oceans.
