Not sure what you're asking when it comes to the cups. As long as you aren't introducing moisture to it there shouldn't be any issues when it comes to mixing kno3, with aluminum, and sulfur. If you are adding some sort of wetting agent to this then you should add 2% boric acid to avoid any exothermic reactions as it dries.

Thanks

Any latex or rubber gloves will work. You can get them in the dish washing supplies at Walmart, or if you want something higher end you can search for chemical resistant gloves on amazon. Only real threats of most potassium perchlorate based flash powders blowing up in your face are from static spark, or just being crazy rough in the handling of it. I do use plastic containers but it is best to avoid using plastic as much as possible because plastic does generate static electricity. As long as you use potassium perchlorate as your oxidizer the flash powder shouldn't be very sensitive. Just be aware of ignition sources such as static electricity or smokers around your shoot sight

I manufacture a lot of canister shells with bottom shots and large canister salute shells. The bottom shot on a 6" shell will hold 1100 or more grams of flash. A 4" salute casing will hold over 400 grams of flash, and a 6" will hold over 2200 grams. Anybody manufacturing many canister salute shells, or multi break shells with bottom shots is going to be mixing up to 10lbs of flash at a time. If you watch Dirty Jobs season 4 episode 16 you'll see Albert Knoblach(owner of Little Big Shots) have Mike Row mix up 10 pounds of this same flash composition or very similar to it.

If you watch Dirty Jobs season 4 episode 16 you'll see Albert Knoblach(owner of Little Big Shots) have Mike Row mix up 10 pounds of this same flash composition or very similar to it. I prefer to mix the 3000 grams because I can still pick up my kraft paper. If I mix more than that it wants to fall out the end. If you watch the dirty jobs one you'll see how he has to use a scoop to pick it up. All the pyrotechnic manufacturing companies here in the USA who make salutes are mixing thousands of grams of flash at a time. It you go to www.littlebigshots.net/display-fireworks.html there are 5" ultra salutes for sale that will contain over 2000 grams of flash. Of course unless you have something like a type 54 fireworks shooters license you can not purchase these. If this was insanity you would hear about places blowing up all the time being a lot of places are doing this 5 days a week.I'm yet to hear of anyone screen mixing flash having any accidents. Normally the guys running into issues are these guys doing this in their garage or house. The problem isn't the flash normally, it's the simple fact that they're doing this where there is an ignition source that sets it off. Just a couple years ago a guy I know had a warehouse and was storing some of his chemicals in there. Was in there running a grinder. Ended up catching fire and burning the entire place to the ground.

Schwagstock is Labor Day Weekend this year and I'll be back there helping set up the show again. If you're on facebook look up Schwagstock 51. I'm not building too much at the moment, because I'm about out of kno3. Supposed to be picking some up while at Schwagstock if Display Pyrotechnics is able to get a decent price on drums at the pgi convention going on right now. I live between Cabool and Houston on highway 63. My main thing is making shells. I make canisters up to 6" and round shells up to 12". Come about October I'll most likely get started on making shells for next year. If you happen to live in this area I'm sure we can get together.

I've heard there is a reaction or something where the kclo4 in contact with sulfur "decays" into kclo3 very slowly.

Not exactly sure if it's safe to mix kno3 with mg or not. Know that the mg will oxide quickly unless you treat it with potassium dichromate before mixing it with kno3. you can get a subscription to fireworking.com for $50 a year. Someone on that site will know the right answer to your question. That's where I ask questions concerning pyrotechnics if I can't find the answer any where else. Only limit I know of is the 10 pounds max at a time for flash powder. Not sure of the details any more. The atf orange book is where you can find the details of it.

@@brandongibbons6618 In modern Pyrotechnics there is absolutely no reason to use MG for any flash in any Size: The shift away from magnesium-sulfur flash powders to perchlorate-aluminum combinations in modern pyrotechnics is driven by a focus on safety, stability, and predictability. Mg-S flash powders are simply too sensitive, dangerous, and prone to accidental ignition, while perchlorate-aluminum flash powders offer a safer and more manageable alternative, complying with modern safety and legal standards.

Here in the USA just about every pyrotechnic company that manufactures salute shells or shells with bottom shots are screen mixing up to 10 pounds of flash at a time. Know for a fact this is how Albert at Little Big Shots does it being he had Mike Row screen mix 10 pounds of flash on Dirty Jobs. Know A&M Pyrotechnics and Zambelli fireworks screen mix about 10 pounds of flash at a time. I'm yet to hear of any of the manufacturers who do this having any issues as this is a safest way to mix bulk amounts of flash. Now should people be mixing multiple pounds of flash who aren't manufacturing lots of salute shells or shells with bottom shots no. For those of us going through 100s of pounds of flash powder manufacturing salute shells this is what we're dealing with and how it's done. Those of us holding or working for a company with an atf type 20 manufacturing license are limited to mixing a max of 10 pounds of flash at a time. People who have obviously never worked for a company that manufactures salutes, or attended the pgi convention posting how things are n't safe that are standard practice is why I no longer post how to videos even though a ton of people aske me to. The only thing that isn't the industry standard being demonstrated here is that I use a stainless steel screen rather than brass.

@@brandongibbons6618is there a certain mixture thats safer than others ? Example the 70% potassium perchlorate and 30% aluminum , is that one of the most stable mixtures? Any mixtures that stand out to you as really dangerous?

The composition is the standard 3 part comp 65%kclo4, 25%blackhead, and 10%sulfur. Not sure why anyone would use an inferior oxidizer like kno3 when it comes to making flash for large aerial salute shells and bottom shots. The way I mix flash is the same way just about every pyrotechnic manufacturer here in the USA does if they're manufacturing a lot of salute shells or shells with bottom shots. Albert at Little Big Shots was on Dirty Jobs, and this same exact method is how he had Mike Row mix 10 pounds of flash. This is also how A&M Pyrotechnics mixes theirs and so does Zambelli fireworks. Now if you're not in the manufacturing game where you're making 1000s of salute shells every year this method probably isn't for you.

En mi canal tengo truenos hechos con nitrato de potasio y suena bien fuerte cuando se comprime.​@@brandongibbons6618

@@brandongibbons6618brother if you were using the standard 70% pp and 30% alu would you still use this method and would you say the standard 70 30 is most stable in your opinion?

It just helps it to not clump up when shipping

I mainly make 4"-12" aerial shells. Gave up on the over priced Chinese crap a long time ago.

😂😂😂💀💀💀💀

Can't really help you on this one. I'm really not sure what TPA is. In order for this comp to work the TPA needs to be a really hot fuel, being just 10% blackhead will not provide enough fuel on it's own.

Blue aluminum can be used to bulk up flash powder, it is not very reactive on its own. Won't even light with standard 70/30 mix.

Is the standard 70 30 pp and Al powder the safest mixture in your opinion ? I know man , wonder what 6lbs of flash would sound like lol ? 😮 that’s a ied not a firecracker lol

@@Bag514 It's been the only one I used so I can't really tell you how it compares to other comps. I put a quarter pound of it in a heading on top of a cohete style 8oz rocket motor and it can barely get above the tree line before it breaks lol. I made several of those and they're insanely loud. I've also made ay least 100 with the smaller 1oz headings and I've never had an issue. I've grown a little more comfortable with it than I was when I started but I try not to get complacent. I still get nervous mixing, I want to try with binary methods more but I know I'll lose volume when I do that. I use a respirator now and run a humidifier nearby for dust mitigation, you'd be surprised how far that aluminum can travel in the air.

I haven't seen where adding sulfur to flash using perchlorate as the oxidizer makes it any more sensitive than the 70/30 mix using just perchlorate and blackhead. It does seem to act as a catalyst like in black powder and seems to make it a little more powerful. Plus it saves you a little money. Mix sulfur with chlorate and you have it becomes much more sensitive. This too has it's uses when making electric matches, or dark flash for breaking crossettes. I would never screen mix a chlorate sulfur mix though. When I made e-matches I used a wet process for it. When mixing dark flash for crossette break I diaper mix it and try to just mix whatever the amount is I need at the time which normally won't be much.

alright. Also i wonder why did you choose to use blackhead aluminum for your compound? Personally i use flash powder pechlorate+magnesium. It seems to be extremely loud in 1.5gram firecracker however i tried a 35gram firecracker and i didn't hear anything at all... That day was very windy, i was and i was in car so there was much noise + i went very very far i assume. When detonate i saw intense flash light and a huge cloud of smoke after but 0 sound 😅

@@thedirector69 Unless you treat magnesium with potassium dichromate it will oxide very quickly especially when combined with an oxidizer. This will cause it to become unreactive so that any salutes made with it won't function properly. If you are using the flash powder shortly after making it this isn't a big issue. Blackhead aluminum actually contains a trace amount of carbon to prevent it from oxidizing. The other reason I use blackhead is because I can get it at a much lower price in 110# drums than I ever can magnesium or magnalium. Think I can get blackhead right now for $6.50 a lb in 110# drum quantities where Magnalium I would have to pay ove $8 a pound for by the drum. Not sure I could find magnesium in a fine enough mesh by the drum right now. I rarely use and magnesium these days so I'm not really up on it's price or availability.

It's been a little over 21 years now. This is how most pyrotechnic manufacturing companies who make aerial salutes and large multi break shells with bottom shots mix flash. Every 6" canister shell with a bottom shot I make requires about 1150 grams of flash. There's a company called Little Big Shots in Pennsylvania. The owner mixes 10lbs of flash at a time. Do to atf regulations 10 lbs is the most you can legally mix at one time. If I was using kclo3 rather than kclo4 I wouldn't screen mix it unless I left the sulfur out and just did a 70/30 mix using only kclo3 and aluminum. Only times I use kclo3 for flash is when I make dark flash for breaking crossetts. Other than for breaking crossetts and making electric matches, I really don't know why anyone would be using kclo3 to make flash.

​@@brandongibbons6618does the addition of sulfur make a big difference in your salutes compared to just a standard 70/30 perc/AL mixture?

@@brandongibbons6618does sulfur make the report louder? Then just doing 65 potassium perchlorate and 35 al ?

There's a Dirty Jobs episode featuring Albert Knoblach, and his company Little Big Shots. He actually has Mike Rowe screen mixes 10lbs of flash for filling 5" salute casings. Not sure how much A&M or Zambeli's mixes at a time but it's well over 6 pounds. Anyone who makes large canister salute shells, or large canister shells with bottom shots are mixing and dealing with large amounts of flash. One 6" salute casing holds about 2500 grams of flash. Even 4" salute casings hold 400 grams. Unless you're doing something incredibly careless it's not going to spontaneously go off. I make 6" tourbillion, serpent, and farfalle shells with bottom shots that take over 8 ounces of 2fa blackpowder to put in the air. If it can take that sort of hit without going off screen mixing certainly shouldn't.

​@@brandongibbons6618& people say I'm crazy for making 1kg of flash.

Se hai una fabbrica che fai 10 grammi??io quando lavoravo facevano pesate anche 10 chili

It's 32 mesh, from mcmaster.com. There should be a link to it on one of the comment responses to this video.

This is the industrial standard for mixing large batches of flash, as shown by Albert of Little Big Shots on an episode of Dirty Jobs. Nobody making 3" and bigger canister salutes and bottom shots are going to be mixing up small batches of flash being it's not only more time consuming it also increases the risk that something does go wrong as your going to be continuously mixing it. My 6" bottom shots hold over 1000 grams of flash, and my 6" canister salutes hold about 2500 grams.

@@brandongibbons6618 That might be in in artesanal shops. Were I live such mixtures are made by machines with wooden or graphitced rubber surfaces, they are inside trenched facilities and are operated remotely, analogous to explosive factories. I cannot fathom how is safe working with such insane amount of flash powder just like that, if that pile somehow ignites its gong to self confine and make a huge explosion that is almost for certain to kill the worker. How is that accepted as "safe"!?! I find so paradoxical and ironic that HEs are deemed so dangerous and beyond the reach the average citizen yet this is ok WTF wouldn't be safer to put some kind of AN based HEs as salute?

@@teresashinkansen9402 some people have their own idea of what’s safe and what isn’t 😂

​@@teresashinkansen9402Look at this pathetic specimen of a safety man, here to tell us everything we're doing wrong in our life.

I was taught to never run metals through a screen.

@@Michael-rg7mx Screen mixing fine nonferrous metals is fine. Mixing larger mesh metals like titanium grapenuts is generally added after the rest of the composition has already been mixed. As a general rule if it's a metal that is fine and will be acting as a fuel you can screen mix it. If it's there to provide sparks it's best to add it after you mix everything else because it's not going to want to pass through the screen.

It does perform a little better and saves you a little money.

Aluminium is expensive and sulfur (usually) cheap, so... Here in Europe the finest Al is almost 6 times as expensive than sulfur. It's probably similar in the US.

@@batbutonfire these are the people who screw things up for everyone and have no clue as to the subject they're talking about. I don't know about other countries but here in the USA almost all your companies manufacturing salute shells of shells with bottom shots are screen mixing their flash and bottom shots. There was actually a Dirty Jobs episode featuring Albert and his company Little Big Shots and he had Mike Rowe screen mix a 10 pound batch of flash. I don't ever mix 10 pounds at a time myself, but that is the max you are legally allowed to mix at once if you read the ATF orange book. Here's a link to a video where Albert is screen mixing star comps and talking about mixing flash to make his 5" salutes. ua-cam.com/video/BDzLPYftERo/v-deo.html

A very powerfull and dangerous firecracker would in my oppinion contain 25 to 30 gram of flashpowder made whit dark german al . But most people dont Even put half that in it and would consider 30g to be insane and wrong

I have made firecrackers that had over 200gram of flash in them

I don't make m80 or quarter stick type firecrackers. The closest thing to that I make are salutes that weigh about 100 grams, and are tied into gas mines to add an audio effect to the fireball. My main use for flash is filling 4" and 6" aerial salutes and bottom shots. I use about 2200 grams in a 6" aerial salute, and about 400 grams in a 4". My 6" bottom shots hold about 1100 grams. When I manufacture salute shells I can go through 18000+ grams of flash in a day. If you're just making small firecracker type salutes I would only mix 1000 grams at once if that. It seems like I read some where that a true m80 contains 3 grams of flash. A quarter stick is impossible to truly making using flash powder being the explosive in dynamite is nitroglycerin.

@@brandongibbons6618sounds like you know your stuff. Subbed.

@@Kirt44😂😂😂😂😂

I've never had any spontaneous ignition. I use this to fill 4", 5", and 6" salute shell casings along with bottom shots. My 6" silver tourbillions with color stars and bottom shot shells, weigh over 8#s and therefore take over 8 ounces of 2fa black powder for lift. If it can take the sort of impact that from over a half pound of bp hitting it without going off it surely shouldn't go off while being ran through a screen. Just watch out for static, and be sure there's no chlorate contamination. If using chlorate as an oxidizer rather than perchlorate then you don't want sulfur any where in the mix unless trying to make a very easy ignition composition for something like making E-matches.

@brandongibbons6618 thank you for your response. There's alot of misinformation specifically regarding flash. I've diapered a lb before for salutes never any issue. People say anything more than 10 grams will go off under its own weight, pretty ridiculous if you ask me. I also use static guard spray and try to keep things clean and methodical. BTW where do you get a screen that big? Homemade ? What mesh screen?

@@hugostiglitz6823 You can get screens of all mesh sizes at www.mcmaster.com/wire-cloth/stainless-steel-wire-cloth-9/ It's a 32 mesh screen. The frame is homemade

i Usually dont add sulfur but becouse I use barium nitrate instead of kclo4 and think that composition is better and more powerfull whitout,

Why aren't you using brass screens ? I have always been told to use non-sparking metal screens when mixing flash . At the WPA Winter blast they require binary mixing in the salute "core". The same company you have linked also sells brass screens.
