Semtex

Why do you say semtex is much more powerful than gelignite?? Msjayhawk (talk) 20:26, 27 April 2008 (UTC)[reply]

Gelignite is not Blasting Gelatin. Blasting Gelatin is either Nitroglycerin or Nitroglycol (92-94%) that is saturated with Guncotton iwth a weight strength of 100% most of the time. Gelignite is mainly a 65% strength with added saw dust or other filler. Msjayhawk 20:36, 5 July 2007 (UTC)[reply]

Quite right. Gelignite and blasting gelatin are two very different explosives. Gelignite is plastic and contains other things besides NG and guncotton while blasting gelatin is just NG and guncotton and is rubbery. It is very powerful but can't be tamped into a hole without leaving air spaces thus lessening its efficiency. Gelignite does burn safely. Some idiots use it to light safety fuse if they don't have a cheesa stick but don't drop it into water or it will explode. Contrary to the article, it does sweat after a while. It also gives you a rotten headache if you have to work with it for long, like making up primers. The article needs to be rewritten. Egoli (talk) 23:03, 21 December 2009 (UTC)[reply]

Questions

The article leaves some questions in my mind.

There is no mention of Roaring Jelly, which I believe was a popular name in the late 1800s. Is RJ gelignite or blasting jelly?

An understandable explanation of the differences between gelignite and blasting jelly is sorely needed. They sound the same. Besides their ingredients, how do they differ as explosives? How do they differ in physical consistency? How do they differ in ease of detonation? Do either of them "sweat" nitroglycerin?

Are there any book citations for answers to these questions? Where are the explosives experts around here? David spector (talk) 04:26, 5 November 2009 (UTC)[reply]
