Nitrating Paper for Combustible Cartridges
Вставка
- Опубліковано 22 лют 2019
- This video provides simple instructions for nitrating paper to be used in Civil War era revolver combustible cartridges.
"Nitrating" is a term that means introducing potassium nitrate into paper so that it burns up more efficiently when fired in a black powder revolver.

A better way to do this would be to boil your water and then add the KNO3 to it. You will get a higher saturation rate since hot water can hold more dissolved KNO3. When you are done, don't throw out the leftover solution, heat it back up to boiling, and then pour about 50% by volume of isopropyl alcohol into the solution, and it will cause the crystals to crash out. Then pour the whole solution through another filter and leave in the sun to dry. You will be left with all of the KNO3 that was left in solution. The powder left over, will be more pure than what you started with.
That's nice information, thank you. However, I've had good results without that. With the exception of the bottom cap not being consumed at all.
I put them on a cookie sheet and dry them at 150 with no problem.
He's not looking to issolate.
@@eddiespencer1issolate? COVID IS OVER
The paper is probably not being significantly nitrated in the strict chemistry sense, as in converting cellulose to nitrocellulose. That requires addition of an acid to convert potassium nitrate into nitric acid. What's actually going on here is simply impregnating the paper with potassium nitrate which then acts as an oxidizer to burn the unmodified celluose molecules... which is almost certainly preferable for making cartridges. Nitrocellulose flash paper tends to be more fragile than the paper it's made from, but this way you get the benefits of burning up all the paper without weakening it, in addition to a much more simple (and safer!) process. Pretty cool!
Agent VX right, he’s just costing the paper with a nitrates solvent and drying it onto it. I’ve done this before when I was recrystallizing kno3 to purify it and filtering it through coffee filters. The filters burn nicely and completely.
I think nitrocellulose would be too unstable to use for cartridges.
It is stable, however it won't be safe. Smokeless powder is made of nitrocellulose. Smokeless powder in a black powder gun is a bad idea.
Doesn't the nitrate change the burn speed of the black powder? By changing the Ratio of nitrate already in the powder
Shane Briggs The burn rate of the black powder stays the same. It just helps with eliminating the paper residue.
"my wifes not here so i can do a lot of this without being observed" BROOOOOO that earned a subscriber by itself
In early childhood, in the early seventies, almost every boy of the great Soviet Union knew Potassium nitrate ... We soaked newspapers in solution and used them in youthful pyrotechnics. Thank you so much for your interesting channel, I always watch it with interest ........ Uvchi to you!
When I was younger one could by a 5 pound box of potassium nitrate and other chemicals at many pharmacys. No longer. Some of the chemicals are no longer sold to the public and most are not sold because very few people have an interest in them.
When I was a boy growing up in the late 70's it seemed we always had easy access to all things that can be mixed to go boom. We liked making booms and other than an occasional larger than normal boom within the city limits of our tiny town requiring our lone policeman to inquire that everyone still had all their body parts no one paid much attention to it. Now we would be put on terrorist lists and jailed. Sad times we live in.
“I can do a lot of this without being observed “..., hehehe. The skills of a married man.
He is a master of the stealth craft. Aka100+ sneak skill
Jeff foxworthy's routine about the similarities between gay men and married men is spot on funny,btw. Lol.
Now I finally understand how it is paper can be used without them leaving a bunch of ash or unburned paper behind. The paper's nitrated. Clever.
Just a recommendation for anyone trying to do this if you can't find a stump remover that doesn't have a bunch of additives try going to the canning section in the grocery store or your Pharmacy and look for what's called saltpeter saltpeter is always at least in my experience 100% potassium nitrate and can also be used for canning things. Also much cleaner and safer. Than stump remover.
If you don't have potassium nitrate(stump remover),you can obtain potassium nitrate from ammonium nitrate plus non sodium salt and water.You can obtain potassium nitrate cristals.
I bought a pound of it from a local chemical company that just so happened to be advertising on eBay. I think I've used two cups of it so far, and I have made a LOT of paper cartridges, more or less, using Era's Gone instructions here in this video (I had a couple hundred coffee filters that didn't fit any coffee maker I own, so I used those)
Salt petre is the old name for potassium nitrate. When I first moved here, salt petre was just down the shelf from flowers of sulfur. Today, neither is as easy to find. Pure potassium nitrate stump remover is easier to find, but even that requires careful label reading.
@@dennisthemenace3695 I live in South Mississippi. You bought 5 pounds? In which section of the store?
@@dennisthemenace3695 Thank you!
I tried it, made a bunch of cartridges, shot them and found that not all the paper burned out and actually created a barrier between the nipple hole and the barrier. Long story suggestion, if you are new make sure the chamber is clear before reloading!
I buy Potassium Nitrate pellets add them to boiling water until the water quits taking /dissolving the pellets. I then let the whole mess cool then strain it to remove undissolved pellets, I use this residue to make another batch of solution adding pellets as long as the solution will dissolve more. I use quart canning jars to store the solution and then soak the paper as usual. I use old tracked computer printing paper, it is substantial enough to wrap the cartridges, and burns almost as well as flash paper and is just as good actually better as heavier coffee filter paper is while burning more completely. Duda Deisel is a good source for the Potassium Nitrate, the pellets they sell are almost pure. Even less expensive is finding a farmer who uses Potassium Nitrate for fertilizer, a farmer with a large operation often buys in multiple Dump Truck loads, some will even give a polite person several pounds. Learning to be polite pays off well, I once was given a full 5 gallon bucket full in return for information as to how to make the paper cartridges. For a reloader, 5 gallons of pellets should last for years. Finding the old obsolete tracked printer output paper is getting more difficult. Thin Onion Skin paper will work almost as well; go to a stationery store and look for the thinnest onionskin paper you can find, Staples is also a good place to look for the paper. Good luck with the process, experimentation and trial and error with. the paper was necessary for me. A friend has found a source for TEA BAG paper that has never given a misfire and has proven to be substantial enough to work with. Patience and experience will teach you how to make these cartridges, Videos like this good one provide a good place to start. Happy loading and shooting! I've followed the directions of the Video, it is effective and a good place to start, but practice and adaptability will give improved results.
Thanks very much, never made paper cartridges before.i shot just muzzle loader rifles and flint lock pistols ,never revolvers. Can't wait and thanks again my new Friend in Arms
I did the same thing for making combustible cartridge for a percussion Sharps Carbine. To make sure my cartridges were robust I used some scrap cotton sheets, cut to 8.5 inches by 11 inches . Once the sheets had soaked up the super saturated mix. I hung them out to dry in the shower and once dry I put them in a plastic container used for leftovers. It was then used to make into cartridges for the Sharps. Good presentation, they'll help a bunch of people out.
Try (36g) potassium nitrate, mixed with (24g) of standard granulated sugar, or a 3 part to 2 part ratio, mix it together in a container by shaking, heat a pan with about 1/3 cup water( or enough to dissolve the amount you have made), bring to a boil, add in your mixed composition, continue boiling until almost all water is boiled away and solution becomes a frothy like consistency, add in your paper or some string if you wanna make some slow burn fuse, let the material soak up the composition, let dry, and you have some pretty decent burning paper/fuse.
Thanks for posting, a suggestion to allow for better absorption is to use warm water. As a solution warm water can absorb more of what is being dissolved. Is why when you make iced tea it's better to sweeten it while it's hot/warm.
I love the bullet mold. I bought your mold with my first cap and ball revolver only a couple months ago. I'm hooked purchased my third revolver stainless 1860 colt gen 2, next step paper cartridges.
Thanks Blutrax, I appreciate the kind words.
You can pure high grade potassium nitrate from a fireworks hobbyist chemical supply location. That’s where I get all of my high grade quality potassium nitrate. No need to buy the stump remover which is fairly low grade.
I also use all natural “Raw” cigarette papers. Thinner, just as strong, and when nitrated burns really well and ignites with a homemade primer a lot better, I also dry my papers in a dehydrator.
Thank you, you just answered most of my questions. Happy new year.
Love this video. Feels like having a good gun friend helping me to learn. I’m new to the hobby. Lots to learn and I love it.
Ten out of ten. Thank you for posting! Love your molds I bought.
I love how black powder shooting slowly turns your into the Betty Crocker of shooting. When you get your first old revolver and powder flash, you feel like this is the most grizzled badass thing you've ever done. Fast forward a couple years. "ok you can make an AMAZING patch lube out of this left over beef fat and beezwax I got from hobby lobby (you can use coconut oil if you want :)"
powder flask* lol
I have a local compounding pharmacy that stocks reagent grade potassium nitrate, sulfur, and powdered charcoal. It's handy for black powder experiments. You use less liquid making black powder, but you still have to dissolve the KN03 to nitrate the sulfur and carbon, then cake, dry, grind and sieve.
I use a couple of old screens. Sandwich them in and out them in the sun. They stay nice and flat.
Thanks. Great video! I bought the same stump remover and was planning on trying to nitrate paper soon but was unsure of the nitrate to water ratio. Glad to see that it can be recycled over & over again.
Great video!
O so this is we’re you get your info ooooo
Thank you very much . Now I know you made it easier than I thought . Once again thank you .
I boiled the same powder but with a higher concentration. End result is a very saturated paper that's sandy but it lit up on a test burn very similar to flash paper. It left no trace behind. This method works.
Thanks buddy! You make it look simple! I’m going to try that
Thanks mark I can't wait to get some, I have a couple of tree stumps from last year that need killen, this way I can justify it to my wife and get a little extra for me. Great video by the way all your videos are informative.
Some of the other methods involve boiling down liquid products to get the potassium nitrate, which carries a risk of ignition. This is the best method so far, relatively easy and safe.
Personally I don't like the 'cook down' methods, too dangerous for me.
risk of ignition?
if you boil to dry and somehow get a fuel in there, sure
The KN03 does not inhibit 'activity' in the stump. It increases activity by feeding microbes that rise in number until the nitrate is used up and then they eat the stump.
He is talking about if the stump is still a living tree it will kill it.
You know, I always thought you were supposed to drill holes in the stump, pour that stuff in, then light it on fire. I didn't know it was supposed to speed up the rotting. So I never used it to remove a small stump in my yard ... instead I paid a gardener a lot of money to remove it. I guess I should have read the instructions.
@@vincentlok8894 different kind of stump remover
I was hoping someone would make a decent video about this I’ve been looking for months
Tea bag paper will almost completely burn up into ashes when set alight. I experimented with combustible paper musket cartridges using tea bag filter paper and always had complete combustion with no embers. Its a little more fragile then coffee filter paper, but the cartridge can still be handled without bursting so long as you wrap the paper at least 2 times around the cartridge.
Kyle Gammage if you use a saturate solution it will all burn completely on coffee filter paper.
Great video. You can use the potassium nitrate and other ingredients to make solid fuel rocket engines for large model rockets too. This stuff can be explosive and its fumes can be dangerous. Use gloves when handling this stuff. You don't want it to get into your skin. Treat it like gun powder.
This looks like a good project for a future date. Thumb up for the information.
This is not nitrating the paper. This is impregnating the paper with nitrates.
So its burning action and not detonation. Just me thinking.
Thank you for sharing!
Jeff
Yes, this is only designed to help the paper burn up completely when the powder charge goes off
@@erasgonehistoricalmolds2400 aha, so the paper is still filled with blackpowder and the paper is there to hold the shot together for fast loading?
@@jeffjefferson2676 Exactly, I explain how to make combustable cartridges in some of my other videos.
Thanks Mark for this video. I made up some potassium nitrate mix a while back and I see now that I put in a bit much water. Mine did burn but it was very slow. I'll do up another batch as you did and go from there.
Thanks, good luck on the next batch
I’ve tried this a few times, and tested the resulting cartridges. I eventually decided that the small difference in leftover paper bits in the chambers wasn’t worth the extra time and effort of nitrating the paper. One test was to fire 100 un-treated perm paper cartridges from the same gun in one shooting session. I figure that if I can get off 100 shots without the little leftover paper bits becoming a problem, then nitrating provides no actual benefit to the shooting and gun cleaning process. And sure enough, that is what I found. Using perm papers, I haven’t nitrated my paper in years and years. There is some leftover paper in the chambers, of course, but it’s never caused a problem, and so what’s the big deal?
So let’s see your 100-shot tests, people!
By the time you’ve made and fired 100 nitrated and another 100 non-nitrated cartridges you’ll definitely be feeling the difference in the processing between the two. Ask me how I know.
Your mileage will vary according to the specific paper you’re using, and if you like spending the extra time and money to make your nitrated cartridges, then OK, but if you want to save time by skipping that process, then it is entirely doable by selecting a different paper. Just keep in mind that a little bit of leftover paper shards in your chambers are not necessarily going to be any sort of problem whatsoever.
I just ordered one of your molds . I have a mold for the Lee conical that casts 6 at a time. Lee has blank molds the size of the 6 molds they have. I wish you offered a 6 mold. I wish would pick up the mandrel idea that Manley's left behind and start making them again-RIP Mr. Manley, I would if I had an adequate workshop.
Excellent. Exactly what I needed. Thanks
I have used flash paper and flash glue. It is harder to work with and more delicate, but when fired it leaves the chamber spottlessly clean. It is also safe to use because it was used in the manufacter of original paper and skin (lamb appendix intestine) cartridges. I have used it manytimes in my repro 1851 and 1860 revolvers with round balls. I always lube the front of each chamber with my home made lube of Tallow, beeswax, and olive oil. I want to make more once EG molds are available again and I can buy them.
Thank you Mark, we appreciate your informative videos!
If you heat the water you can get more Nitrate in solution. Of course as water cools the nitrate will drop out of solution.242g/liter at 20C and 2,439g/liter at 100C.
Hi Mark. Thanks for all the great videos you make and all the information you share with us curious souls out here, it is very much appreciated.
I’ve just recently done this with another powdered product available a few months ago, used distilled water though. Brought two four cups to a boil in a pot, put it in a large sealer jar and stirred it while adding the stump remover until it no longer was dissolving. Created a super solution which I use on the coffee filters. Some crystals of potassium nitrate formed on the bottom, so I know there is more than enough suspended in the water.
I keep the sealer jar in a cool dry place in my workroom and haven’t had a problem with slime forming in the water, maybe due to using the distilled water?
Keep the videos coming, very much enjoy the history and information you provide.
Cheers
Thanks John. Yes if you heat the water the solution will hold much more of the potassium Nitrate. But it may also start to precipitate out of solution as the liquid cools if it is over saturated. That is not a big deal, however, it will still work with crystals floating in the solution. Using distilled water will definitely prevent introducing other chemicals, such as lime, chlorine and fluoride into the solution, I'm just not sure how much difference that will make in the long run. Thanks again!
Great video.. Thanks for the upload.. Been 40 years but getting back into the black powder and never thought of trying paper cartridges.. Your info has helped a lot and looking forward to the results. Might try both the brown filters.. but then also try some rice paper as it seems to burn up more fully and faster than the coffee filters. Again, thanks for the information.
Just an appreciative note for the fine videos. I have just finished a lengthy casting session with Eras Gone Colt. 36
and the Richmond .36. Both fine products that drop from the mold easily. My question is where does one purchase a fine looking Eras Gone ball cap such as you are wearing?
Try some NITRATE model airplane dope! Really it will make tissue or silkspan or other paper go up in a flash. Bodaks hobby supplies has what is needed, like your VIDEOS! !!-!!
helpful hint (from a professional chemist): at room temperature, the potassium nitrate will dissolve in water at about 1:3 by weight (that is, one pound of potassium nitrate to 3 pounds water) - if you heat the water to just under boiling, that ratio goes up to about 5:2 (5 pounds of potassium nitrate to 2 pounds water) - so heat your water before dissolving the powder, you'll get a lot more into solution, and by extension, a lot more impregnated into your coffee filters
helpful question (or suggestion): can you do a demonstration of igniting the paper with a percussion cap? and a side-by-side of nitrated paper vs non-nitrated paper burning?
Thanks. Learned about you from Mike Bellaveau duelist1954.
Thanks for watching!
I went with cigarette papers for making paper cartridges, still haven't fired any, just tried rolling up a few, but since I have read others have had it work, I thought I would invest a few dollars and experiment with it. My only worry is possible hang fires as the cap goes off and then the paper has to burn through before the pyrodex lights up.
That's been my findings. I tear off the bottom of the cartridge. Works great for me that way.
Thank you. I use tea bag filter papers instead of coffee filter paper. That's the only thing I do different.
Try Duda Diesel for Potassium Nitrate, mix the dry granules until the water will not take anymore hot, water works best. We used this by the ton for commercial farming. I hear that it now requires a permit for large quantities as potassium nitrate mixed with the right amount of diesel fuel makes a potent explosive.
I bought from Duda, They have 1lb,5lb,10lb and 50lb bags. Actually you use ammonium nitrate and diesel fuel to make an explosive. I used that to blow tree stumps, 1 or 2 tomato paste size cans would do the deed if placed right. Very similar to TNT and much cheaper. You do have to get a permit for Ammo.Nitrate of over 16% purity ever since Oklahoma Bombing.
@@Merlinemryys We once bought Potassium Nitrate by the ton to replace the plant nutrients that cotton took out of the soil, we also rotated the crops by using Alfalfa for a few years. Potassium Nitrate accelerated the process. Usually we saved some out for making Corned Beef and other things. I wasn'trequired by Duda Deisel ti get a permit, probably because the amounts I ordered were small enough that they're not considered dangerous. I do know that without Saltpeter, Corned Beef is a nasty unappetizing gray color, it takes only a little bit in the brine to preserve the color. Good luck with your cartridge building. Saltpeter and Potassium Nitrate are synonymous, it along with high grade sulphur and Alder charcoal are the ingredients essential for Black Powder. Alder charcoal is the best, though other kinds are also used for this purpose.
Always good to see how others do this..... good vid... 🙂
I saturate water in a spray bottle and then spray the cartridges after they’re made. Cuz I’m lazy and figure since it’s saturated it shouldn’t dissolve the stuff in the black powder.
Trying to find stump remover in this town....everywhere is sold out. They must have watched your video!
Try Lowe's.
Amazon sells it
I love this! Just did it today. 3 things:
1. Adding sulfur seems to make the burn faster. Is there a reason not to do this?
2. Rice paper seems to be a cleaner burn, but harder to handle.
3. For faster drying, could you make the solution with isopropyl alcohol?
I'd ask a chemist about point 3. It probably would dry faster, but you might be altering the composition of the solution in a way you don't want to.
Thank you for your video. Most helpful.
Homedepo had stump killer but it wasn't potassium nitrate. Lowes is the place to go.
Thanks Mark, but if Mrs. Hubbs catches you using her kitchen tools you may be The Hubbs Gone.
Thanks for posting Mark. Very informative and useful.
If you want to make flash paper/ nitrocellulose add sulfuric acid + potassium nitrate or nitric acid, let paper sit over night and rinse with water and let dry. Make sure to have a bucket of water that has been mixed with sodium carbonate "baking soda" if it gets out of control this solution will neutralize the acids. These two acids when mixed will heat up and produce gas so make sure to be under a vent hood with a mask or outside away from anything you care about. UA-cam has a tutorial if you need to watch.
Ok, slight out of the box question on paper cartridges. I'm curious has anyone tried making paper cartridges for a modern inline muzzleloader? I've had several people tell me I should be using loose power instead of pellets. I use the pellets manly out of convenience, but this looks like a good way to have that convenience and use loose power at the same time.
Yes you can. I've been shooting paper cartridge's for three years out of my encore and traditions. One 209 primer the tradition is no 11 .
Excellent video! Thank you very much.
Very helpful Mark, thx.
Thanks, and this gave me other ideas, too!
Thanks very informative 👍
at first I was thinking the solution would be what you would use to make gun cotton, but then I realised that would change the load and affect the chamber pressure a great deal and probably be dangerous!
Spectracide is the only brand that is nearly pure KNO3, Only brand that is KNO3-boiling water dissolve more. 242g/L at 20C, 2439g/L at 100C
this is not nitrating of paper, its just paper soaked in oxidizer nothing more... actual nitration of paper requires concentrated sulfuric acid mixed with either potassium nitrate or nitric acid...
Iam; Well, that would be Nitrocellulose. For out purposes, the term nitrated paper is descriptive and useful.
@@KB4QAA i guess nitrocellulose would be way better to use instead that "nitrated paper", there are modern weapons that use nitrocellulose casing...
Nitration of paper into nitrocellulose might cause extremely high pressures as it will become a propellant.
@@snowflakemelter1172 The amount of paper is tiny, probably 1 or 2 grains. Not enough to swamp the larger powder load.
@@ApplyWithCaution Huh? Nitrocellulose vs. KNO3; Your comment makes no sense.
read the sds for PPE - gloves
Thanks so much for sharing that!
Get an Old food dehydrator could come in handy, when there’s no sunlight.
very helpful, thank you.
The same formula one would use with hemp/cotton rope to make a slow match for a matchlock muzzleloader
Yes, or slow match for 18th Century artillery, which I've made a bunch of.
Nice job Mark!!
Zigzag works just fine for me
Great info!! Thanks!
I have a question. I use end wraps used in hair styling. It burns well and fast, but I wind up with a lot of unburnt residue. I wonder how much impact glue stick glue has on incineration? Has anyone tested this?
That is always a possibility. I had much more trouble when I used to use clear glue. I sometime still get end caps that stay in the chamber unburnt. It could be a result of using too much glue stick. They would have usd a wheat based paste in the old days. Any paste made with a starch base should burn better than a modern adhesive using polymers or acrylics.
@@erasgonehistoricalmolds2400 If ya got a recipe, great, if not, I'll see what I can find out about it. Thanks!
@@erasgonehistoricalmolds2400 a little late to the party but i imagine that boiling or simmering some form or either flour or possibly corn starch would probably yield a decent adhesive with good enough burn rate. Possibly with a very small amount of Elmer's school glue if the adhesion isnt good enough? Just speculating because that is not a property for adhesives that was ever a consideration for me; other than avoiding solvent explosions lol.
@@erasgonehistoricalmolds2400 I also seem to recall nitrocellulose being a polymer. May be able to dissolve a ping pong ball in some acetone to make a readily flammable adhesive. I would however advise caution for that one.
Nitrocellulose dissolves in acetone and it usually referred to as "Colloidon". It used to be used for repairing cine film. You can still get it as "Plastic Skin" as it has a use medically for covering scratches and other minor injuries.. be warned, it stings like **!!@@"!!! Don't know if you can get it in your corner of the swamp, but might be worth trying...!
did not know it was that easy
Could you dissolve charcoal and sulfur in the mix also and have the paper burn even better?
The paper is already very much fuel "rich" for the quantity of nitrate it can be impregnated with. Adding more fuel would not help, but hinder complete combustion of the cartridge-
On top of that, although a couple of things like carbon disulfide or hot toluene WILL dissolve Sulfur but not paper, charcoal doesn't dissolve in much of ANYTHING, let alone any solvent which wouldn't also destroy the paper.
You would be making what I have heard called touch paper if you use the correct proportions.
Thank you sir. That was very helpful
Will you have more Johnston and Dow moulds for sale?
Someone please educate me, can I use that nitrate to make DIY black powder for muzzle loaders??
Yes
I'm sort of a noob when it comes to paper cartridges but I just use thin hemp rolling papers and a piece of chalkboard chalk for my 1851s I just roll up the paper like a cigarette around the piece of chalk with the wad and ball set at the tip fill it with my charge from my flask cut it flat and flush and rip a smaller square of another paper to lick and glue over the exposed powder so my caps only have to blast through 1 thin layer instead of folding the end over and gluing it down and the caps having the caps trying to blast through 2 layers of rolling paper
Does this seem like a decent way to make them?
That’s way cheaper than buying magician flash paper
With all the respect you and others deserve, why use coffee filters? It is porous paper and could let the moisture in... whoudn't be better something else? Like brown supermerket paper bags? I tried coffee filters but it's just too much of a snug on the chamber (.36 / .375 round) I use cigarette paper that is "slow burning" :-( Still looking for a situable paper. Cheers!
You can buy KNO3 at the burg store; look for saltpeter.
Educational, thanks.
Use hot water to melt the KNO3. I buy a bag of potassium nitrate from the feed and fertilizer store. It’s 99.99 percent pure. It’s never felled any thing I want to make. Especially my fireworks.
Pickling salt for pistols. So now you have a pickled pistol? Hahaha
I saw alot of carbon left over from the paper burn and I am now curious if adding a small percentage of sulphuric acid to the paper would lessen it with out adding too much combustiability to it.
What about combustible nitrocellulose cartridges? Table tennis balls are made of nitrocellulose. In acetone, they dissolve and form a gel that could be used to make combustible cartridge cases. However, for black powder weapons, gas pressure and burning rate will be too high.
awesome vid sir thanks for the tips
KNO3 solubility in H2O:133g/L @ 0c, 242g/L @20c, 2439g/L @ 100c
Try A: Using the hottest water you can, with the maximum ammount of nitrate it will hold in solution for impregnating your filter paper, and-
B: Try misting the papers you withdraw wet from the hot solution with some alcohol from a spray bottle, which will cause the nitrate to crash out of solution in place, rather than dripping away in the excess water draining off the paper. Your papers will also dry a bit faster due to some water having been displaced by the alcohol. You could use denatured ethanol sold in the paint area of a hardware store, or even 70% isopropyl rubbing alcohol, don't use methanol (toxicity issues).
If you do try this, weigh some samples of your papers produced with alternate methods and see just how much weight per square inch of retained nitrate different methods of impregnation get you. Because, it's not science unless you take notes, kids!
I used this method using old bed sheet, cotton, to make "linen" cartridges for my percussion Sharps carbine. I used boiling water to dissolve the potasium nitrate.
I have test fired some real linen cloth cartridges in my Sharps. They ingnited and burn up perfectly without any potassium nitrate in the cloth.
@@erasgonehistoricalmolds2400 Like I said, I was using cotton sheets and I wanted to be sure that they burned up when I fired them.
Excellent video
Thanks, Mauser!
So question for any folks who do this, thoughts on doing this as charges for a Flintlock?
Use hot water
Nice video. Funny I posted a video this morning on testing nitrated paper. Used the method to make the solution.
Thanks Sixshooter. I see your curling papers burn about the same as the coffee filters.
@@erasgonehistoricalmolds2400 . Mlm..
Actually I understand that you want them to dry FLAT because if you hang them the potassium solution will run down to the edges so to speak where as flat it stays evenly distributed..
John, that might help some, but probably not enough to really make a different for paper. When I make slow match for my cannon I do that, because I want the cotton cord to have a consistent burn rate along its entire length.
We’re the original paper revolver cartridges of the 1860s potassium nitrate coated like this or did they use paper converted to nitrocellulose (flash paper) for complete and rapid combustion?
There were several patents for combustable and "waterproof" cartridges. I suspect some of them were nitrocellulose based. Some were just paper and some appear to have been nitrated as in this video.
Wow cool
