Asphaltite (also known as uintahite, asphaltum, gilsonite or oil sands [1]) is a naturally occurring soluble solid hydrocarbon, a form of asphalt [2] (or bitumen) with a relatively high melting temperature.
Prior to the 20th century, the term asphaltum was in general use. [3] The word derives from the Ancient Greek word ἄσφαλτος ( ásphaltos ), which referred to natural bitumen or pitch. The largest natural deposit of bitumen in the world is the Pitch Lake of southwest Trinidad , which is estimated to contain 10 million tons.

A flash powder composition may specify multiple different fuels. Some fuels can also serve as binders. Common fuels include: Metals. Aluminium – most common fuel in many classes of mixtures, also a combustion instability suppressant. Less energy per mass than carbon but less gas evolution, retaining heat in the reaction mixture.
