Nitrocellulose

Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms. It was also used to replace gunpowder as a low-order explosive in mining and other applications. In the form of collodion it was also a critical component in an early photographic emulsion, the use of which revolutionized photography in the 1860s.

Examples of use of gun-cotton
1. Multimedia extras introduce visitors to the environs above and below sea level with a 1'0' cityscape taken from across the Halifax Harbour, and animated surveys of the harbour‘s ‘topography.‘ Next, City of Ruins recounts the fatal collision on the morning of Dec. 6 between the relief ship, Imo, and the munitions–laden Mont Blanc – the latter carrying over 2,500 tons of benzol fuel, TNT, picric acid, and gun cotton. (The explosion threw one of the ship‘s gun barrels more than three miles inland, lifted a Navy tug entirely out of the water and onto a nearby pier, and drove a 60–foot wall of water over the Halifax shoreline.) Here, extras include profiles of the ships involved and a "historical docu–comic" paying tribute to the city‘s firefighters.
