Youngfolk's Book of Invention We do not hear of blasting with gunpowder until the seventeenth century, and even a hundred years later the amount used for that purpose was very small. Blasting gelatine was used to pierce the great St. Gothard Railway tunnel through rock so hard that without it the task could never have been accomplished. Blasting gelatine was tried in guns, but burst them, so Nobel set himself to discover an explosive less violent, yet equally clear and smokeless. www.usgennet.org /usa/topic/preservation/science/inventions/chpt22.htm   (2040 words)

Peterman   (Site not responding. Last check: 2007-11-03) Much ingenuity was called for in devising slow burning fuses, some being made from connecting straws filled with finely ground fl powder, or from paper twists which had been impregnated with wetted gunpowder and then dried. The other items shown include a stick of Special Gelatine, an ice-lolly stick favoured by many as an innocuous tamping tool, a torch battery, and–yes–that is a condom, of which more later. These are used in circumstances where a large amount of material is being blasted and a sequential series of explosions is preferable. www.peterman.org.uk /explosives.htm   (1086 words)

EGDN,Blasting Gelatine,Myrol - The Explosives and Weapons Forum I love very much nitric esters and i think that blasting gelatine is one of the best HE because of its power and because it is relatively easy to prepare. One of my blasting handbooks says that the BG has a metastable detonation without the bubbles, but stable det can be achieved by small (10 grams) PETN or RDX initiating charge or (this is the important thing) by kneading BG thoroughly, because this should (presumably) put new bubbles into it. I always make my blasting gelatine with homemade nitrocellulose and i can say that it worked well but surely it is too expensive to make NC so i decided to try with smokeless powder. www.roguesci.org /theforum/showthread.php?t=4329   (3642 words)

Junior Science - Research Assignment This was followed by his invention of a form of blasting gelatine called ballistite, made from a mixture of nitroglycerine and nitrocellulose. However, the blasting gelatine called ballistite that he invented was smokeless. Hence, it was used by the military as a smokeless explosive which would not give away an artilleryman's position to the enemy, and would reduce the fouling of rifle barrels. members.tripod.com /qldscienceteachers/junior/intro/research.html   (524 words)

Astrolite (Arno Hahma; Gerald L. Hurst) Blasting gelatine (in a borehole) outperforms TNT by a factor of about 2. The cracks are not a problem with liquid slurries, since the slurries are used with large boreholes (50 mm and up) and with larger distances from hole to hole. It does not evolve gaseous ammonia on mixing, like the astrolites do and it is about as sensitive as freshly prepared Astrolite G. For rock blasting you need a relatively slow detonating explosive with a large gas volume. www.yarchive.net /explosives/astrolite.html   (3030 words)
