dynomike1 Posted November 7, 2012 Posted November 7, 2012 So what you are saying Dag is i have to mill BP wet it rice it dry it then mill it again to use it on a carrier? Jwitt what i was thinking about an addition to Charcoal streamer stars is maybe putting flying fish fuse or falling leaf or crackling fuse or small bottle rockets or maybe even aerial spinners in some shells but i got to get my BP worked out first. Just say i'm lazy and don't have much available time right now.

bob Posted November 7, 2012 Posted November 7, 2012 straw makes dangerously sensitive BP. How do you know straw makes sensitive bp? Im not saying your wrong I just dont know and would like to know if you have gotton this from a good source or made it your selfbob

Im not saying your wrong I just dont know and would like to know if you have gotton this from a good source or made it your selfbob British Military used undercooked Rye straw , it was called "Cocoa powder", very sensitive stuff can't find the source of the info, I'll keep looking Edited November 7, 2012 by Algenco

Mumbles Posted November 7, 2012 Posted November 7, 2012 There is information on Cocoa powder in Chemistry of Powder and Explosives by Davis I believe.

dynomike1 Posted November 8, 2012 Posted November 8, 2012 I got my dehydrater in the yard with Bp in it after about an hr it burns a little better but hard to light seem like we have had a high humidity week here. This weekend i am going to make another batch i am going to dry it then mill it if it doesnt work i still have a bunch of FG i can mill. If we ever get through planting wheat i will have more time to do this.Hard to figure these tubs have only been opend twice but maybe they already had moisture in them.
bob Posted November 9, 2012 Posted November 9, 2012 how under cooked was it? like when the gases start to light or some thing?I wonder how sensitive it is I mean if the military used it it can't be that sensitive. I'd like to try making some (in a very safe location ie small mill in a large hole and stuff over it so if it does blow nothing will happen)but I don't know if I ever will it might be to risky
dan999ification Posted November 9, 2012 Posted November 9, 2012 (edited) it is said that opening the hessian sack it was stored in would generate enough static to ignite it.Undercooked as in still brown with nearly all volatiles burned off, og cooks paulownia to perfection ( still brown) i too have cooked brown charcoal and was told it was undercooked, until og went into more detail about it, it is significantly faster in bp and the charcoal takes fire easier than if you cooked the granny out of it.I would stay away from cocoa powder and try the more reactive charcoals first cooking to perfection. Dan.Edit, i have also found mill dust hard to light at times with a smouldering stick and even a lighter, once granulated this changes. Edited November 9, 2012 by dan999ification

Mumbles Posted November 12, 2012 Posted November 12, 2012 While it was alleged to be quite sensitive, it was also quite low powered. A typical cocoa powder mix had 5% or less sulfur, and was made into very large grains for firing cannons and other projectiles. The low powered propellant allowed for lighter cannons and less stress. I've seen reports that it can be used for smaller arms too, but I don't know what sort of formulas were used, or in what applications. The majority of the information I've read on it are in regard to the large grain cannon propellant. To give you an idea, it was completely phased out 130 years ago with the advent of the first smokeless powders. It sounds to me that it has a similar burning characteristic, where it needed high pressures to function as intended.
