The size of the explosive charges ranged from to of blasting gelatin.
2.
The explosive used in the shells themselves was actually a " desensitized blasting gelatin " composed of nitrocellulose and nitroglycerine.
3.
By 1918, the practice had evolved to use blasting gelatin, a mixture of nitroglycerin, guncotton and wood pulp.
4.
Blasting gelatin, also known as " gelignite ", was invented by Nobel in 1875, using nitroglycerin, wood pulp, and sodium or potassium nitrates.
5.
Gelignite, or blasting gelatin, as it was named, was patented in 1876; and was followed by a host of similar combinations, modified by the addition of potassium nitrate and various other substances.
6.
It also found use as a " productive " desensitizer ( one that contributes to the overall power of the explosion rather than having a neutral or negative effect ) in nitroglycerine and nitroglycol-based explosives such as dynamite and blasting gelatin.
7.
Nobel later combined nitroglycerin with various nitrocellulose compounds, similar to collodion, but settled on a more efficient recipe combining another nitrate explosive, and obtained a transparent, jelly-like substance, which was a more powerful explosive than dynamite .'Gelignite', or blasting gelatin, as it was named, was patented in 1876; and was followed by a host of similar combinations, modified by the addition of potassium nitrate and various other substances.
