Does anyone know the mixture for Black Powder?(Gunpowder)?
83085
"By weight measure, black powder is made of seventy-five parts saltpeter finely ground, fifteen parts charcoal, and ten parts sulfur. All ingredients must be fine ground separately. This can be accomplished with either a mortar and pestle, or with a hand-cranked flour mill. Never mix all three ingredients before grinding unless you want to turn your mill into a deadly grenade, or your mortar into a cannon that can blow off your fingers or even your hand."\n\nDont forget that gunpowder is a low-explosive. it will not explode in the open atmosphere, but will explode under compretion. In other words, dont keep it in an airtight container.\nBE CAREFULL!!! Remember, flamible things tend  to burn!;-)

You need to buy some books. I don't say that lightly - in the past I have offered specific reloading data for people. But the way you worded your question suggests that reloading is new for you, and I assure you there's more to reloading than simply dropping the right amount of powder into a shell.\n\nBuy yourself a couple of decent reloading manuals - the RCBS manual is probably the best overall shotshell manual, and you can supplement that with load data from Alliant's website, as you're using Red Dot.

um i don't know if this site has it, but you might want to try chemguide.co.uk :) it's a pretty good site.

well...im not going to tell you how to make gunpowder, but a pretty fun home made 'bomb' can be made out of a tennis ball, some match sticks and lots of duck tape. It takes ages but;\n\nchop the tips off matches (wear gloves)\ncut a small slit in a tennis ball and stuff the matchheads in, as many as you can. Wrap the whole thing in duck tape so its really airtight.\n\nNow, to set the thing off, just throw it really hard at a wall or something (for gods sake dont throw it at someone) The matchheads will ignite and the pressure build up will cause the tennis ball to rupture giving a nice satisfying bang. \n\ngood thing about this is you cant commit a terrorist outrage with it, and its not powerful enough to really harm anybody - but still, be careful when you use it, dont dick around because if it goes off in your hand it could do some damage - the noise is really loud too - you dont want to go deaf. Bottom line is - the thing might take up to a minute to actually blow up (usually takes a few seconds but still), dont throw it at something then wander over and pick it up again!!\n\nhave fun and dont kill anybody\nhope this helps

ammonium nitrate and aluminum hydroxide\n\nNH4NO3 + Al(OH)3\n\nThe aluminum hydroxide is insoluble when formed and will precipitate out of the solution as a solid powder.

umm maybe not that mixture hehehe I would have to look in my cookbook\nbut yes, many many common household products can be used to make explosives and explosive devices

extract it with an appropriate solvent. it could be water, alcohol, or maybe hexane. this depends on the solubility of the substance your after. then you could freeze dry it to remove the solvent and all your left is the powder form.

cotton, tobacco, opium, just to name a few. But do some of your own research! :-)

Back in the early Hollywood days, they used to use a slingshot to shoot a small piece of chalk. Seemed to work fairly well. Used in a lot of the old Westerns, especially against a rock or other similar hard back- ground. I don't know if you could find "black chalk" to simulate a bullet hole against a light surface, or interior wall. Good luck.

no it cant be black unless it is producing an extremely incomplete combustion but here is what you can do to color a flame through the use of chemical compounds/elements:\nRED FLAME=lithium (CAUTION PRODUCES STONG REACTION WITH WATER) , strontium chloride, or calcium carbonate\nYELLOW FLAME=sodium(CAUTION PRODUCES STONG REACTION WITH WATER)\nWHITE=zincwill produce a slightly greenish white flame(CAUTION PRODUCES TOXIC FUMES)\nGREEN=anything with copper except for its salts or phosphates when moistened with undilluted sulphuric acid(CAUTION PRODUCES TOXIC FUMES), antimony or barium\nBLUE=arsenic(CAUTION TOXIC), lead(CAUTION TOXIC), selenium(CAUTION TOXIC), or bismuth(CAUTION TOXIC), one nontoxic compound is antimony or ammonium compounds if done in a well ventilates place.\nPURPLE=Potassium(CAUTION REACTS STRONGLY WITH WATER) except for borates, phosphates and silicates,or mix of strontium and copper\nAs noted some of thes produce toxic fumes or are toxic themselves so be careful

Gunpowder, whether black powder or smokeless powder, is a substance that burns very rapidly and is used as a propellant in firearms. As it burns, a subsonic deflagration wave is produced rather than the supersonic detonation wave which high explosives would produce. This reduces peak pressures in a gun, but makes it less suitable for shattering rock or fortifications.\n\nBlack powder is a mix of sulphur, charcoal, and potassium or sodium nitrate, (sodium nitrate makes a less powerful compound), at a weight ratio of approximately 10:15:75, respectively, though the ratios can vary somewhat depending on the purpose of the powder. Unlike smokeless propellants, it acts more like an explosive since its burn rate is not affected by pressure, but it is a very poor explosive because it has a very slow decomposition rate and therefore a very low brisance. This same property that makes it a poor explosive makes it useful as a propellant — the lack of brisance keeps the black powder from shattering the barrel, and directs the energy to propelling the bullet. Historically, potassium nitrate was extracted from manure by a process superficially similar to composting. Nitre beds took about a year to produce crystallized potassium nitrate.

Charcoal powder will burn very well.\nThe flame used to ignite the powder will not be affected and will not change color.\nThe charcoal dust will burn yellow/white.  It will be that color because your experiment lacks enough oxygen for it to burn blue.\n\nOther dusts are very flammable and sometimes are explosive.  The dust from grain when stored in a silo is extremely flammable. Silos across the country explode every year.\nCoal is crushed into dust and blown into the furnaces at electrical power plants.  The heat makes steam for the turbine/generators.  \n\nI would like to suggest some experiments with common powders to see how well they burn.  But I singed the hair off both hands, my brother singed off his eyebrows, and we decided playing with fire was (though great fun) rather stupid.

Here is a "recipe" for gun bluing\n\nBlue-Black Finish on Steel\n \na. Place object in molten sodium nitrate (700-800 degrees F) for 2-3 minutes. Remove and allow to cool somewhat; wash in hot water; dry and oil with mineral or linseed oil. \n\nb. Place in following solution for 15 minutes:\nCopper sulphate 1/2 oz.\nIron Chloride 1 lb.\nHydrochloric acid 4 oz.\nNitric acid 1/2 oz.\nWater 1 gallon\nThen allow to dry for several hours; place in above solution again for 15 minutes; remove and dry for 10 hours. Place in boiling water for 1/2 hour; dry and scratch brush very lightly. Oil with mineral or linseed oil and wipe dry.

Geez... the history of the gun.... Let's see... Well, it was invented not so long after the introduction of black powder... man this will take waaaay too long and I don't have that much time... I suggest you watch the History Channel... they have a great series on the history of the gun... \nand it "might" be any age... geez

Let me start by warning you not to attempt to make gun powder.  It is extremely hazardous and you can be killed or seriously burned while trying to make it.  The grinding process can very easily set it off.  If you want black powder, you can buy it at many sporting goods stores that sell muzzle loading rifles.  DO NOT ATTEMPT TO MAKE IT YOURSELF.\n\nBlack powder can be made by grinding together 2 parts charcoal, 3 parts sulfur and 15 parts potassium nitrate.  Once ground together (if you survive) the powder tends to separate with agitation and must be remixed each time before loading into a gun.  You can avoid this problem to some extent by mixing the ingredients with a little water to form a paste.  Allow the paste to dry and then grind into a coarse powder with the consistency about like grits or Cream of Wheat.  This grinding process is also extremely hazardous and can kill you.\n\nRemember, many people have tried making gun powder and have ended up loosing eyes, fingers, hands, arms and even then lives.  It ain't a project for a curious armature.  DON'T MAKE IT....JUST BUY IT IF YOU MUST HAVE IT.  Even then, it is a hazardous substance to handle.  Get proper instruction before handling it.  The best advice is don't make it, buy it or handle it.  Just read about it and leave it alone unless you own a muzzle loader which is made to use it.  Then get proper instructions for handling both the powder and the gun.

For yours and others sake, I hope you don't find out. Gunpowder is dangerous stuff and should not be made by people.
