Dr-D, The reason your BP simply burned fiercely is because it wasnt a very good quality mix. Good quality blackpowder depends mainly on the type of charcoal. Charcoals made from softwoods are the best and the only kind that will make some kind of "explosive" black powder. DO NOT use charcoal used for cooking food! It contains things such as glues and lighter fluid. Even after you get those out (you can) the charcoal is still from a hardwood. Because ideally when your cooking you want a long lasting burn from your charcoal, this is where the hardwoods come in. But with blackpowder you a charcoal that burns FAST. Willow being the most common. High quality charcoal can also be made from dried grass etc.. Charcoal is always of a black colour. If it is grey/white, its been completely burned and is useless to you. Even if you get that done, the proportions for black powder are important, adding too much of anything will make it burn significantly slower. The ideal ratio is 75% KNO3, 15% charcoal and 10% S The black powder needs to go through a series of steps before it becomes useful aswell. First the potassium nitrate, sulfur and charcoal need to have the finest particle size you can get. This can be achieved through the simple yet time consuming mortar and pestle method ( dont use a wooden set, use a brass or ceramic mortar and pestle set ). Or the best way is to use a ball mill. However you get it done, what you have is still only green meal, it is still quite useless. It must then be compressed into cakes with or without the aid of a solvent to bind the loose powder. Which is then to be rammed to the density of approximately 1.8g/cc and crumbled into small little chunks. Then what you have is a useful powder. capable of making salutes, and launching powdered napthalene(god that stuff smells, Heh) to make small fireballs =] These are the steps the commercial black powder manufacturers use. If a simple propellant with the least amount of labour involved is desired, look at the topic thread under Explosives>Vitamin C GunPowder. |

you can buy PDCB here on the east side under the name of "Enoz" or "Enox" moth cyrstals. and megalomania can you give me a detailed procedrue for making benzene from these, and what state do you live in? maybe it is a restricted state lik NJ or something. ------------------ "... always look on the positive side of things, blow things up not down" -- Ragnar Benson |

What percentage by weight would you add the Napthalene to the AN? Would it be a good sensitizer, like nitromethane, or would it make an explosive as hard to detonate as ANFO? Like would it become sensitive to a # 8 cap? Thankz for any help, cause napthalene mothballs are easy to find where I am. |

hmm. Well I'd say using smokeless powder would be better than going through all the trouble of making good BP. I don't have access to hardly any good tools. I have a few amounts of smokless powder that I am saving for good uses only, ill test out a batch. |
