Guncotton Dynamite

Guncotton Dynamites were brisant expls, but their density was low and they required large bore-holes...

Dumorite. Accdg to Refs 1 3 it was a Guncotton Dynamite of high density contg 35 to 40 more l%x8 inch sticks to the case than the ordinary Dynamite. It was waterproof, and non-freezing, but too insensitive to be of use in ditch-blasting by the propagation method...

Around the same time, nitration of cellulose to produce nitrocellulose (NC also known as guncotton) was undertaken by different groups and finally the invention of NC was reported by Schonbein (Basel) and Bottger (Frankfurt) independently in 1846. Further, dynamite was invented by Alfred B. Nobel in 1866. 

Note Since the above powdery expls contain Na nitrate, they have been sometimes called "Powdery Dynamites with Explosive Base . The same applies to expls contg K nitrate. There have been, however, powdery Dynamites which contained real expl ingredients (lijre NC) in addn to NG. To such expls belongs Abel s Dynamite contg NG 65.5, powdered Guncotton 30.0, K nitrate 3.50 Na carbonate, patented in... 

Demolition Explosives (Demolition Blocks, Demolition Charges and,Demolition Devices) (See also Demolition Hoses, Demolition Kits and Demolition Snakes). Demolition expls are those used for demolition purposes. They are mostly HE s (such as TNT, PA, Tetryl, FETN, Dynamite, etc), made in the shape of blocks, cartridges, etc. Some LE s, such as compressed wet Guncotton, can also be used. Under the term Demolition Devices, Ohart (Ref 8) described Bangalore Torpedoes (See Vol 2, P 16"R of this Encycl) and various demolition blocks, including shaped charges. In Ref 12a, the same devices are listed as Demolition Materials (qv)... 

TNA shows about the same sensitivity as tetryl in the drop test. Lead block experiments have been reported which showed that 10 grams of TNA produced a net expansion of 430 cc., TNT 254 cc., picric acid 297 cc., tetryl 375 cc., guncotton 290 cc., and 75 per cent dynamite 300 cc.76 Experiments with the manometric bomb gave the results indicated below. 

Uses Nitroglycerin (or glyceryltrinitrate) is a pale yellow, oily liquid also available in the form of rhombic crystals. It is highly explosive. It is used in combination with ethylene glycol dinitrite in the manufacture of dynamites, explosives, rocket propellants, smokeless powders, and guncotton. 

Trauzl and Abel proposed a dynamite with an active base consisting of guncotton and charcoal for absorption of the nitroglycerine.
