Dynamite is usually rated by "weight strength" (the amount of nitroglycerin it contains), usually from 20% to 60%. For example, 40% dynamite is composed of 40% nitroglycerin and 60% "dope" (the absorbent storage medium mixed with the stabilizer and any additives).
Bickford's fuse not only dramatically improved the safety conditions of mines around the world, but also contributed to the development of dynamite. Alfred Nobel created dynamite in 1867, by moulding nitroglycerine and a mud-like compound found near his laboratories called kieselguhr into individual cylinders. [ 10 ]
Nitroglycerin (NG) (alternative spelling of nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.
It was September 15th, 1959, when an ex-convict, 49-year-old Paul Orgeron showed up on the campus of Edgar Allen Poe Elementary with his seven year old son and a suitcase packed with dynamite.
Military dynamite has approximately 60% of the strength of nitroglycerin-based, commercial dynamite. This statement is unclear. Grades of commercial dynamite were rated by the percent of nitroglycerin, commonly 30%, 40% or 60% nitroglycerin depending on use (in quarrying, lower percentile to move rock, higher percentile to shatter rock).
Contrary to urban legend, an M-80 that contains 3,000 mg of powder is not equivalent to a quarter-stick of dynamite. Dynamite generally contains a stable nitroglycerin-based high explosive, whereas M-80s or any other kind of firecracker contain a low explosive powder, like flash powder or black powder. [10]
