==Non-dynamite explosives== Other explosives are often referred to or confused with dynamite: ===Trinitrotoluene (TNT)=== [[Trinitrotoluene]] (TNT) is often assumed to be the same as (or confused for) dynamite largely because of the ubiquity of both explosives during the 20th century. This incorrect connection between TNT and dynamite was enhanced by cartoons such as [[Bugs Bunny]], where animators labeled any kind of bomb (ranging from sticks of dynamite to kegs of [[black powder]]) as TNT, because the initialism was shorter and more memorable and did not require [[literacy]] to recognize that TNT meant "bomb".{{cn|date=August 2022}} Aside from both being high explosives, TNT and dynamite have little in common. TNT is a second-generation [[Use forms of explosives#Castings|castable explosive]] adopted by the military, while dynamite, in contrast, has never been popular in warfare because it degenerates quickly under severe conditions and can be detonated by either fire or a wayward bullet. The German armed forces adopted TNT as a filling for artillery shells in 1902, some 40 years after the invention of dynamite, which is a first-generation [[phlegmatized explosive]] primarily intended for civilian earthmoving. TNT has never been popular or widespread in civilian earthmoving, as it is considerably more expensive and less powerful by weight than dynamite,<ref name=Meyer2008>J. Köhler, R. Meyer, A. Homburg: ''Explosivstoffe''. Zehnte, vollständig überarbeitete Auflage. Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim 2008, {{ISBN|978-3-527-32009-7}}.</ref> as well as being slower to mix and pack into boreholes. TNT's primary asset is its remarkable insensitivity and stability: it is waterproof and incapable of detonating without the extreme shock and heat provided by a [[blasting cap]] (or a [[sympathetic detonation]]); this stability also allows it to be melted at {{convert|178|F|C|order=flip}}, poured into [[shell (projectile)|high explosive shells]] and allowed to re-solidify, with no extra danger or change in the TNT's characteristics.<ref>Gibbs, T. R. & Popolato, A. ''LASL Explosive Property Data''. [[Los Alamos National Laboratory]], New Mexico. [[United States Department of Energy]], 1980.</ref> Accordingly, more than 90% of the TNT produced in the United States was always for the military market, with most TNT used for filling shells, [[hand grenades]] and [[aerial bombs]], and the remainder being packaged in brown "bricks" (not red cylinders) for use as [[satchel charge|demolition charges]] by [[combat engineers]]. ==="Extra" dynamite=== In the United States, in 1885, the chemist Russell S. Penniman invented "ammonium dynamite", a form of explosive that used [[ammonium nitrate]] as a substitute for the more costly nitroglycerin. Ammonium nitrate has only 85% of the [[chemical energy]] of nitroglycerin.<ref>{{Cite web |title=FHWA - Center for Local Aid Support - Publications |url=https://www.fhwa.dot.gov/clas/ctip/context_sensitive_rock_slope_design/ch_3_3.aspx#3_1_3_1 |access-date=2024-03-31 |website=[[Federal Highway Administration|Federal Highway Administration (FHWA)]]}}</ref> It is rated by either "weight strength" (the amount of ammonium nitrate in the medium) or "cartridge strength" (the [[Strength (explosive)|potential explosive strength]] generated by an amount of explosive of a certain density and grain size used in comparison to the explosive strength generated by an equivalent density and grain size of a standard explosive). For example, high-explosive ''65% Extra dynamite'' has a weight strength of 65% ammonium nitrate and 35% "dope" (the absorbent medium mixed with the stabilizers and additives). Its "cartridge strength" would be its weight in pounds times its strength in relation to an equal amount of [[ANFO]] (the civilian baseline standard) or [[TNT]] (the military baseline standard). For example, 65% ammonium dynamite with a 20% cartridge strength would mean the stick was equal to an equivalent weight strength of 20% ANFO. ==="Military dynamite"=== "Military dynamite" (or M1 dynamite) is a dynamite substitute made with more stable ingredients than nitroglycerin.<ref>{{Cite book |last=Ledgard |first=Jared |url=https://books.google.com/books?id=U6f-Qlmm6zIC&pg=PA498 |title=A Soldiers Handbook, Volume 1: Explosives Operations |publisher=Jared Ledgard |year=2007 |isbn=978-0-615-14794-9 |access-date=13 December 2015 |archive-url=https://web.archive.org/web/20220125091923/https://books.google.com/books?id=U6f-Qlmm6zIC&pg=PA498 |archive-date=25 January 2022 |url-status=live}}</ref> It contains 75% [[RDX]], 15% TNT and 10% desensitizers and plasticizers. It has only 60% [[TNT_equivalent#Relative_effectiveness_factor|equivalent strength]] as commercial dynamite, but is much safer to store and handle.<ref>{{Cite book |last=Jones |first=Jeffrey |url=https://books.google.com/books?id=g5w6DwAAQBAJ&dq=military+dynamite+composition&pg=PA267 |title=U.S. Marine Corps School Of Infantry SOI Complete Training Materials |date=2017-10-19 |publisher=Jeffrey Frank Jones |pages=AM1401-6 |language=en}}</ref>
