It’s not like you can make gunpowder from everyday, household materials Homemade Firearms Right? Incoming Fire Sharp as a Marble - Excuse me while I whip out my hypothesis on 3/6/2012 10:19 AM Comments Craig says: on 3/6/2012 at 7:05 AM I'm not sure I would label that mixture as 'gunpowder'....... But it DOES make a wonderful smoke-bomb. In the 8th grade (a LOONG, long time ago) saltpeter was a LOT easier to come by and my Jr Hi school used to get filled with that smoke on a regular basis. At least until the routineness of the act became passe'. Robb Allen says: on 3/6/2012 at 8:34 AM Craig, it most definitely isn't what you and I would call gunpowder, but it is a precursor that is relatively simple to make. A little more effort and you could readily have something that would produce enough gas fast enough to use in a firearm. Might not be as reliable as the store bought stuff, but the point is that everything that makes a firearm can be made at home with the right equipment and thus, bans are as useless as a book on economics is to a Congressweasel. Stuart the Viking says: on 3/6/2012 at 10:08 AM Now mix this post with the last post and go shoot a match using ammo loaded with home-made gunpowder! Hehe... dare ya... double dog dare ya! Oh, and I would suggest an OUTDOOR match. s Kaerius says: on 3/6/2012 at 10:50 AM Pff. When I was a kid I mixed black powder using proper salpeter(from spice packets bought at the grocery store), charcoal(for barbeque grill), and sulphur(from a paint shop, 1kg jar). The only step I skipped that prevented it from being real proper gunpowder was boiling the mixture and crushing the resulting cake... I just mixed it in proper quantities(with a mortar and pestle) and used as is. I never did use up that jar of sulphur... went to hazardous waste disposal years later mostly full. Kaerius says: on 3/6/2012 at 10:56 AM Btw: I had the recepie for more proper modern gunpowder, but even back then, nitric acid was a pain to get ahold of, for a kid of 12 years old or so.. IE: Nitrocellulouse, dipping cotton in a mixture of 3 parts nitric acid and 1 part sulphuric acid. Jake says: on 3/6/2012 at 11:07 AM The compulsive modernist urge to quantify and commodify means we can make lab instruments from trash. [Emphasis mine] And here they hit on a key concept the statists don't seem to understand. This is why bans on things like methamphetamine consistently fail. I'm not sure I would label that mixture as 'gunpowder' They do make a note of that: Real gunpowder contains saltpeter, sulfur and charcoal. However, this home recipe should be more than enough for all your pyromaniacal needs. As for making real gunpowder, charcoal is easy to get, but I'm not sure offhand where you would get sulfur from common household materials.
